g


Answer:_______________




 

1)  

5 similar watches weigh 360 g more than 2 similar clocks.
If one watch weighs 100 g, how heavy is one clock

Answer: 70 g


SOLUTION 1 :

Step 1: Weight of 5 watches → 100 g x 5 = 500 g
Step 2: Weight of 2 clocks → 500 g - 360 g = 140 g
Step 3: Weight of 1 clock → 140 g ÷ 2 = 70 g

One clock is 70 g.



2)  

5 similar watches weigh 390 g more than 2 similar clocks.
If one watch weighs 180 g, how heavy is one clock

Answer: 255 g


SOLUTION 1 :

Step 1: Weight of 5 watches → 180 g x 5 = 900 g
Step 2: Weight of 2 clocks → 900 g - 390 g = 510 g
Step 3: Weight of 1 clock → 510 g ÷ 2 = 255 g

One clock is 255 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 370 g more than 2 similar clocks.
If one watch weighs 100 g, how heavy is one clock

Answer: 65 g


SOLUTION 1 :

Step 1: Weight of 5 watches → 100 g x 5 = 500 g
Step 2: Weight of 2 clocks → 500 g - 370 g = 130 g
Step 3: Weight of 1 clock → 130 g ÷ 2 = 65 g

One clock is 65 g.



5)  

5 similar watches weigh 290 g more than 2 similar clocks.
If one watch weighs 200 g, how heavy is one clock

Answer: 355 g


SOLUTION 1 :

Step 1: Weight of 5 watches → 200 g x 5 = 1000 g
Step 2: Weight of 2 clocks → 1000 g - 290 g = 710 g
Step 3: Weight of 1 clock → 710 g ÷ 2 = 355 g

One clock is 355 g.



6)  

5 similar watches weigh 280 g more than 2 similar clocks.
If one watch weighs 230 g, how heavy is one clock

Answer: 435 g


SOLUTION 1 :

Step 1: Weight of 5 watches → 230 g x 5 = 1150 g
Step 2: Weight of 2 clocks → 1150 g - 280 g = 870 g
Step 3: Weight of 1 clock → 870 g ÷ 2 = 435 g

One clock is 435 g.



7)  

5 similar watches weigh 350 g more than 2 similar clocks.
If one watch weighs 160 g, how heavy is one clock

Answer: 225 g


SOLUTION 1 :

Step 1: Weight of 5 watches → 160 g x 5 = 800 g
Step 2: Weight of 2 clocks → 800 g - 350 g = 450 g
Step 3: Weight of 1 clock → 450 g ÷ 2 = 225 g

One clock is 225 g.



8)  

5 similar watches weigh 380 g more than 2 similar clocks.
If one watch weighs 180 g, how heavy is one clock

Answer: 260 g


SOLUTION 1 :

Step 1: Weight of 5 watches → 180 g x 5 = 900 g
Step 2: Weight of 2 clocks → 900 g - 380 g = 520 g
Step 3: Weight of 1 clock → 520 g ÷ 2 = 260 g

One clock is 260 g.



9)  

5 similar watches weigh 370 g more than 2 similar clocks.
If one watch weighs 220 g, how heavy is one clock

Answer: 365 g


SOLUTION 1 :

Step 1: Weight of 5 watches → 220 g x 5 = 1100 g
Step 2: Weight of 2 clocks → 1100 g - 370 g = 730 g
Step 3: Weight of 1 clock → 730 g ÷ 2 = 365 g

One clock is 365 g.



10)  

5 similar watches weigh 300 g more than 2 similar clocks.
If one watch weighs 120 g, how heavy is one clock

Answer: 150 g


SOLUTION 1 :

Step 1: Weight of 5 watches → 120 g x 5 = 600 g
Step 2: Weight of 2 clocks → 600 g - 300 g = 300 g
Step 3: Weight of 1 clock → 300 g ÷ 2 = 150 g

One clock is 150 g.
