Hello!

For #1, the LCD is (A) 12 since both numbers go into 12 as their minimal number.

For #2, the missing number is (B) 4 because 1/4*4/4=4/16.

For #3, the answer is (B) 3 because you have to crossmultiply 20n(4*15) to find the answer.

for #4, the correct answer is (A) 4/5 is less than 5/6 because when converted into fractions with a common denominator, 24/30 is less than 25/30.

For #5, the LCD is 36; therefore, the answer is (A) because the fractions in the answer are properly converted to their new denominator.

I really hope I helped!
A.) The first one is 12 because the lowest multiple of both 12 and 4 

B.) The second one is 4 because if you were to multiply the denominator of the left fraction by 4 to get 16 (which is the same as the right fraction), then you multiply the numerator by 4 to get 4

D.) The third one is 5 because if you were to create the same denominators on both fractions, you would have to multiply the left denominator and numerator by 5

A.) The fourth one is A because the right fraction is an improper fraction, which means it is a mixed number. ( A whole number and a fraction)


A.) The fifth one is A because the LCD of the fractions is 36.
