1) In order to add or subtract fractions denominator must be equal
Lcm of denominator is 4×5=20 since they are co primes
Now the denominator becomes same
2)
Lcm =8
3)
We just need to add the fractions
Lcm=12
hope it helps :)

To know the amount of eights you want to get something that looks like ?/8. Basically, the bottom number needs multiplying by 2 (8 divided by 4 is 2). To keep the fraction accurate you multiply by 2 the top and bottom number so you get:
<span>3/4=(3x2)/(4x2)=6/8</span>
Answer:
c) 14
Step-by-step explanation:
Find the prime factorization of 98
98 = 2 × 7 × 7
Find the prime factorization of 126
126 = 2 × 3 × 3 × 7
To find the GCF, multiply all the prime factors common to both numbers:
Therefore, GCF = 2 × 7
GCF = 14
Have a good day and stay safe!
