What is

plus

Step-by-step explanation:

2/4 + 3/5

LCM = 20

2/4 = 2*5/4*5 = 10/20

3/5 = 3*4/5*4 = 12/20

2/4 + 3/5 = 10/20 + 12/20   = 22/20

24+35= 1 1/10

Solution with Steps

24+35=?

The fractions have unlike denominators. First, find the Least Common Denominator and rewrite the fractions with the common denominator.

LCD(2/4, 3/5) = 20

Multiply both the numerator and denominator of each fraction by the number that makes its denominator equal the LCD. This is basically multiplying each fraction by 1.

(24×55)+(35×44)=?

Complete the multiplication and the equation becomes

1020+1220=?

The two fractions now have like denominators so you can add the numerators.

Then:

10+1220=2220

This fraction can be reduced by dividing both the numerator and denominator by the Greatest Common Factor of 22 and 20 using

GCF(22,20) = 2

22÷220÷2= 1 1/10

The fraction

1 1/10

is the same as

11÷10

Convert to a mixed number using

long division for 11 ÷ 10 = 1R1, so

1 1/10

Therefore:

24+35=1 1/10

Hope this helps ;)

b, i believe, but not sure.
