Question

(4^-1+8^-1) divide (2/3)^-1

~♥~ ​

Answer 1

Step-by-step explanation:

When adding unlike fractions (unlike or dissimilar fractions are fractions with different denominators); we find the least common denominator (LCD):

We list all of the denominators; divide by the common factor of the denominators(Note: Division should result with whole numbers otherwise you just retain the number like 3):

3 4 8 / 4

3 1 2

We multiply all the factors : 4 * 3 * 1 * 2 = 24, this will be our LCD

1/3 + 1/4 + 1/8 = 8/24 + 6/24 + 3/24 = 17/24
