Decimal 4641

The sum of two decimal numbers, one of the numbers is 3.2, larger than the other, is 52.78.

Correct answer:

a =  27.99

Step-by-step explanation:


a=b+3.2
a+b=52.78

a-b = 3.2
a+b = 52.78

Row 2 - Row 1 → Row 2
a-b = 3.2
2b = 49.58


b = 49.58/2 = 24.79
a = 3.2+b = 3.2+24.79 = 27.99

a = 2799/100 = 27.99
b = 2479/100 = 24.79
