Increase 70kg in a ratio of 3/4:1/2

Answer 1

To increase 70kg in a ratio of 3/4:1/2, we need to find the total parts of the ratio:

3/4 + 1/2 = 6/8 + 4/8 = 10/8

This means we need to divide 70kg into 10 equal parts:

70kg ÷ 10 = 7kg

Now we can multiply each part of the ratio by 7kg to find the corresponding increases:

3/4 ratio: (3/4) x 7kg = 5.25kg increase
1/2 ratio: (1/2) x 7kg = 3.5kg increase

Therefore, the increase in the ratio of 3/4:1/2 is 5.25kg and 3.5kg respectively, for a total increase of 8.75kg.

To find the new total weight:

70kg + 8.75kg = 78.75kg
