Answer:
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
Answer: 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!!! Good luck!!! ;)
