Question

Ram did two parts of a cake in the ratio 3 : 7 . Find each part in percentage?​

Answer 1

Step-by-step explanation:

Ram did two parts of a cake in the ratio 3:73:7

Let, the ratio of two parts be 3x,7x3x,7x

The total cake = 100=100 %

The total cake =3x+7x=3x+7x

3x+7x=1003x+7x=100 %

10x=10010x=100 %

x= \frac{100}{10}x=10100

x=10x=10 %

Substitute x=10x=10 % in 3x3x and 7x7x

3x=3\times103x=3×10

= 30=30 %

7x=7\times107x=7×10

= 70=70 %

Therefore, the percentages of each part is 3030 % and 7070 %.

Answer 2

Answer:

Sum of the terms = 3 + 7 = 10

First part = 3/10 x 10 = 3

In percentage = (3/3 + 7) x 100% = 30%

Second part = 7/10 x 10 = 7

In percentage = (7/3+7) x 100 = 70%
