Question

Kirk grew a crystal in science class on monday it was 13 16th of an inch tall it had grown 1/4 inch between friday and monday it has grown 1/2 inch between tuesday and friday how tall was kirks crystal

Answer 1

first we will find a common denominator which is 16
the first fraction doesn't have to change but 1/4 becomes 4/16 and 1/2 becomes 8/16 when you add 13/16 + 4/16 + 8/16 = 25/16 now simplify 1 9/16


`1 (9)/(16)` is your answer
