Question

90 kg in the ratio 2:3:7

Answer 1

To divide 90 kg in the ratio 2:3:7, first find the value of one part by dividing 90 kg by the sum of the ratio. Then, multiply the value of one part with the ratio values to find the weight for each part.

Step-by-step explanation:

The question asks for 90 kg to be divided in the ratio of 2:3:7. To do this, we first add the values of the ratio, which is 2+3+7=12. Then, we divide 90 kg by the sum of the ratio to find the value of one part.

90 kg ÷ 12 = 7.5 kg

Now, we can find the weight for each part of the ratio by multiplying the value of one part with the respective ratio values:

2 parts: 2 x 7.5 kg = 15 kg
3 parts: 3 x 7.5 kg = 22.5 kg
7 parts: 7 x 7.5 kg = 52.5 kg

Answer 2

15 : 22.5 : 52.5

Step-by-step explanation:

2+3+7 = 12units

To find how much kg one unit is.

90kg ÷ 12units = 7.5kg/unit

2units : 7.5 x 2 = 15kg

3units : 7.5 x 3 = 22.5kg OR 22/1/2 kg

7units : 7.5 x 7 = 52.5kg OR 52/1/2 kg

Therefore, the answer is

15 : 22.5 : 52.5
