suppose there are 12 year,14 year, and 16 year cicadas that all appear this yest. after how many years will all three types of cicades appear together again?

We have to find LCM of 12,14,16

Refer to the attachment

LCM=2×2×2×2×3×7=16×21=336years

3/4 ÷ 3/4

step-by-step explanation:

basically divide any proper fraction with itself to fit the criteria.

so if we are using 3/4, then:

3/4 ÷ 3/4 = 1

so 1 is the quotient.

and the numerators for both these fractions is 3.   and if we divide the numerators:

3 ÷ 3 = 1

we see that quotient is equal to our original quotient as well.
