8/21
Step-by-step explanation:
lcm of 7,21=21
3+5/21=8/21
5/21 + 1/7 is 8/21
Find the least common denominator or LCM of the two denominators:
LCM of 21 and 7 is 21
Next, find the equivalent fraction of both fractional numbers with denominator 21For the 1st fraction,
since 21 × 1 = 21,
5/21 = 5 × 1/21 × 1 = 5/21Likewise, for the 2nd fraction,
since 7 × 3 = 21,
17 = 1 × 37 × 3 = 3/21Add the two like fractions:
5/21 + 3/21 = 5 + 3/21 = 8/21
So, 5/21 + 1/7 = 8/21
