Answer:
LCD = 10
Step-by-step explanation:
4/5 = 8/10
1/2 = 5/10
Answer:
1 3/10
Step-by-step explanation:
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.
(45×22)+(12×55)=?
Complete the multiplication and the equation becomes
810+510=?
The two fractions now have like denominators so you can add the numerators.
Then:
8+510=1310
This fraction cannot be reduced.
The fraction
1310
is the same as
13÷10
Convert to a mixed number using
long division for 13 ÷ 10 = 1R3, so
1310=1310
Therefore:
45+12=1310
