Question

A number is 2/5 times another number. If their sum is 70 find the numbers

Answer 1

Answer:

50, 20

Step-by-step explanation:

Let the number be x.

As per the sum,

2/5x + x=70

Taking 5 as the denominator for both,

2/5x+5/5x=70

7/5x=70

x=70×5/7

x=10×5

x=50

Therefore, the numbers are x=50 and 2/5x=2/5×50=20

Answer 2

Answer:50 and 20

Step-by-step explanation:

x+2/5x=70

After taking LCM, we get

(5x+2x)/5=70

5x+2x=70x5

7x=350

x=350/7

x=50

2/5x=2/5x50=20
