Agrade has 81 girls and 72 boys. the grade is split into groups that have the same ratio of girls and boys as the whole grade. how many girls are in a group that has 16 boys?
plz asap

First thing to do is to find the ratio of girls to boys (81:72) simplified to 9:8 respectively by dividing both numversions by 9.

As there are 16 boys in the class, the ratio is multiplindeed by 2, where boys to girls is now 18:16 respectively, and therefore there are 18 girls in the class

The answer for this is 9/1253decimal form 0.007

Hello!

the answer is:

the correct option:

b.

why?

to solve the problem, we need to remember how to operate to simplify exponential expressions using the logarithms.

we are given the equation:

then, using placing logarith with base 7 on both sides of the equation, we have:

so, rounding the obtained result to two decimal places (nearest hundreth), we have:

hence, we have that the correct option:

b.

have a nice day!
