Answer:
1/4
Step-by-step explanation:
The fractions have unlike denominators. First, find the Least Common Denominator and rewrite the fractions with the common denominator.
LCD(1/8, 2/16) = 16
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.
(18×22)+(216×11)=?
Complete the multiplication and the equation becomes
216+216=?
The two fractions now have like denominators so you can add the numerators.
Then:
2+216=416
This fraction can be reduced by dividing both the numerator and denominator by the Greatest Common Factor of 4 and 16 using
GCF(4,16) = 4
4÷416÷4=14
Therefore:
18+216=14
