let's bear in mind that a year has 12 months, so 30 months is really 30/12 years.

7 2/5 x 6 1/4
14/5 x 6/4
84/20
21/5
=4.2
Y=-2x-10
So it would be -2
proportions are just equivalent fractions
-5/-10 would be your answer =)
Answer:
0.3
30%
Step-by-step explanation:
To write 15/50 as a percent, you have to multiply the fraction by 100
x 100
dividing 100 by 50 gives 2
15 x 2 = 30%
to convert 15/50 to a decimal, first simply the fraction.
Both the numerator and denominator can be divided by 5
3/10
the next step is to divide the numerator by the denominator
3/10 = 0.3
