g


Answer:_______________




 

1)  

5 similar watches weigh 350 g more than 2 similar clocks.
If one watch weighs 170 g, how heavy is one clock

Answer: 250 g


SOLUTION 1 :

Step 1: Weight of 5 watches → 170 g x 5 = 850 g
Step 2: Weight of 2 clocks → 850 g - 350 g = 500 g
Step 3: Weight of 1 clock → 500 g ÷ 2 = 250 g

One clock is 250 g.



2)  

5 similar watches weigh 360 g more than 2 similar clocks.
If one watch weighs 130 g, how heavy is one clock

Answer: 145 g


SOLUTION 1 :

Step 1: Weight of 5 watches → 130 g x 5 = 650 g
Step 2: Weight of 2 clocks → 650 g - 360 g = 290 g
Step 3: Weight of 1 clock → 290 g ÷ 2 = 145 g

One clock is 145 g.



3)  

5 similar watches weigh 310 g more than 2 similar clocks.
If one watch weighs 210 g, how heavy is one clock

Answer: 370 g


SOLUTION 1 :

Step 1: Weight of 5 watches → 210 g x 5 = 1050 g
Step 2: Weight of 2 clocks → 1050 g - 310 g = 740 g
Step 3: Weight of 1 clock → 740 g ÷ 2 = 370 g

One clock is 370 g.



4)  

5 similar watches weigh 280 g more than 2 similar clocks.
If one watch weighs 120 g, how heavy is one clock

Answer: 160 g


SOLUTION 1 :

Step 1: Weight of 5 watches → 120 g x 5 = 600 g
Step 2: Weight of 2 clocks → 600 g - 280 g = 320 g
Step 3: Weight of 1 clock → 320 g ÷ 2 = 160 g

One clock is 160 g.



5)  

5 similar watches weigh 320 g more than 2 similar clocks.
If one watch weighs 250 g, how heavy is one clock

Answer: 465 g


SOLUTION 1 :

Step 1: Weight of 5 watches → 250 g x 5 = 1250 g
Step 2: Weight of 2 clocks → 1250 g - 320 g = 930 g
Step 3: Weight of 1 clock → 930 g ÷ 2 = 465 g

One clock is 465 g.



6)  

5 similar watches weigh 250 g more than 2 similar clocks.
If one watch weighs 100 g, how heavy is one clock

Answer: 125 g


SOLUTION 1 :

Step 1: Weight of 5 watches → 100 g x 5 = 500 g
Step 2: Weight of 2 clocks → 500 g - 250 g = 250 g
Step 3: Weight of 1 clock → 250 g ÷ 2 = 125 g

One clock is 125 g.



7)  

5 similar watches weigh 250 g more than 2 similar clocks.
If one watch weighs 170 g, how heavy is one clock

Answer: 300 g


SOLUTION 1 :

Step 1: Weight of 5 watches → 170 g x 5 = 850 g
Step 2: Weight of 2 clocks → 850 g - 250 g = 600 g
Step 3: Weight of 1 clock → 600 g ÷ 2 = 300 g

One clock is 300 g.



8)  

5 similar watches weigh 370 g more than 2 similar clocks.
If one watch weighs 120 g, how heavy is one clock

Answer: 115 g


SOLUTION 1 :

Step 1: Weight of 5 watches → 120 g x 5 = 600 g
Step 2: Weight of 2 clocks → 600 g - 370 g = 230 g
Step 3: Weight of 1 clock → 230 g ÷ 2 = 115 g

One clock is 115 g.



9)  

5 similar watches weigh 390 g more than 2 similar clocks.
If one watch weighs 190 g, how heavy is one clock

Answer: 280 g


SOLUTION 1 :

Step 1: Weight of 5 watches → 190 g x 5 = 950 g
Step 2: Weight of 2 clocks → 950 g - 390 g = 560 g
Step 3: Weight of 1 clock → 560 g ÷ 2 = 280 g

One clock is 280 g.



10)  

5 similar watches weigh 250 g more than 2 similar clocks.
If one watch weighs 180 g, how heavy is one clock

Answer: 325 g


SOLUTION 1 :

Step 1: Weight of 5 watches → 180 g x 5 = 900 g
Step 2: Weight of 2 clocks → 900 g - 250 g = 650 g
Step 3: Weight of 1 clock → 650 g ÷ 2 = 325 g

One clock is 325 g.
