If one watch weighs 190 g, how heavy is one clock

g


Answer:_______________




 

1)  

5 similar watches weigh 320 g more than 2 similar clocks.
If one watch weighs 170 g, how heavy is one clock

Answer: 265 g


SOLUTION 1 :

Step 1: Weight of 5 watches → 170 g x 5 = 850 g
Step 2: Weight of 2 clocks → 850 g - 320 g = 530 g
Step 3: Weight of 1 clock → 530 g ÷ 2 = 265 g

One clock is 265 g.



2)  

5 similar watches weigh 310 g more than 2 similar clocks.
If one watch weighs 140 g, how heavy is one clock

Answer: 195 g


SOLUTION 1 :

Step 1: Weight of 5 watches → 140 g x 5 = 700 g
Step 2: Weight of 2 clocks → 700 g - 310 g = 390 g
Step 3: Weight of 1 clock → 390 g ÷ 2 = 195 g

One clock is 195 g.



3)  

5 similar watches weigh 340 g more than 2 similar clocks.
If one watch weighs 120 g, how heavy is one clock

Answer: 130 g


SOLUTION 1 :

Step 1: Weight of 5 watches → 120 g x 5 = 600 g
Step 2: Weight of 2 clocks → 600 g - 340 g = 260 g
Step 3: Weight of 1 clock → 260 g ÷ 2 = 130 g

One clock is 130 g.



4)  

5 similar watches weigh 320 g more than 2 similar clocks.
If one watch weighs 130 g, how heavy is one clock

Answer: 165 g


SOLUTION 1 :

Step 1: Weight of 5 watches → 130 g x 5 = 650 g
Step 2: Weight of 2 clocks → 650 g - 320 g = 330 g
Step 3: Weight of 1 clock → 330 g ÷ 2 = 165 g

One clock is 165 g.



5)  

5 similar watches weigh 380 g more than 2 similar clocks.
If one watch weighs 120 g, how heavy is one clock

Answer: 110 g


SOLUTION 1 :

Step 1: Weight of 5 watches → 120 g x 5 = 600 g
Step 2: Weight of 2 clocks → 600 g - 380 g = 220 g
Step 3: Weight of 1 clock → 220 g ÷ 2 = 110 g

One clock is 110 g.



6)  

5 similar watches weigh 350 g more than 2 similar clocks.
If one watch weighs 190 g, how heavy is one clock

Answer: 300 g


SOLUTION 1 :

Step 1: Weight of 5 watches → 190 g x 5 = 950 g
Step 2: Weight of 2 clocks → 950 g - 350 g = 600 g
Step 3: Weight of 1 clock → 600 g ÷ 2 = 300 g

One clock is 300 g.



7)  

5 similar watches weigh 310 g more than 2 similar clocks.
If one watch weighs 180 g, how heavy is one clock

Answer: 295 g


SOLUTION 1 :

Step 1: Weight of 5 watches → 180 g x 5 = 900 g
Step 2: Weight of 2 clocks → 900 g - 310 g = 590 g
Step 3: Weight of 1 clock → 590 g ÷ 2 = 295 g

One clock is 295 g.



8)  

5 similar watches weigh 290 g more than 2 similar clocks.
If one watch weighs 120 g, how heavy is one clock

Answer: 155 g


SOLUTION 1 :

Step 1: Weight of 5 watches → 120 g x 5 = 600 g
Step 2: Weight of 2 clocks → 600 g - 290 g = 310 g
Step 3: Weight of 1 clock → 310 g ÷ 2 = 155 g

One clock is 155 g.



9)  

5 similar watches weigh 390 g more than 2 similar clocks.
If one watch weighs 200 g, how heavy is one clock

Answer: 305 g


SOLUTION 1 :

Step 1: Weight of 5 watches → 200 g x 5 = 1000 g
Step 2: Weight of 2 clocks → 1000 g - 390 g = 610 g
Step 3: Weight of 1 clock → 610 g ÷ 2 = 305 g

One clock is 305 g.



10)  

5 similar watches weigh 260 g more than 2 similar clocks.
If one watch weighs 190 g, how heavy is one clock

Answer: 345 g


SOLUTION 1 :

Step 1: Weight of 5 watches → 190 g x 5 = 950 g
Step 2: Weight of 2 clocks → 950 g - 260 g = 690 g
Step 3: Weight of 1 clock → 690 g ÷ 2 = 345 g

One clock is 345 g.
