How to multiply 2 1 /2 multiply 1/10

Okay, this will be simple.

Notice that 2 1/2 is a mixed number. This needs to be changed to an IMPROPER FRACTION.

To do this, multiply the denominator by the whole number

2 x 2 = 4

Add numerator and keep denominator the same.

5/2.

Okay, so 5/2 x 1/10.

When multiplying fractions, no common denominator is needed. Just multiply the numerators and denominators.

5 x 1 = 5

2 x 10 = 20.

5/20 which reduces to 1/4. (5 is the GCF of 5 and 20, 5 divided by 5 = 1 and 20 divided by 5 = 4)

5/20 or 1/4 is your answer. (they mean the same thing)

answer: y = -2.5x - 15
