125 27.3
—— = ——
X 100

125 x 100 = 12500
12500/27.3 = 456.8

First, let's declare a variable

x = # of students

Now, let's create an equation to model the problem.

x * 0.273 = 125

Divide both sides by 0.273

x = 457.8 = 458 students.

Note, I rounded to the nearest whole number.

Simpfily -39 + 3/2(10)
likoan [24]

Answer:

-38.85   or -24

Step-by-step explanation:

What I do is start with the brackets along with the rest of the numbers involved

2(10) is basically 2 x 10= 20

-39 + 3/20

3/20 = 0.15

-39 + 0.15 = -38.85

Unless if 3/2(10) has 3/2 as a fraction, the answer would be -24
