Relate decimals and fractionsOf the 100 students in the fourth grade, 70 students are girls.Write a fraction in tenths and a fraction in hundredths to tell what fraction of the fourth-grade students are girls Question 5 Write a fraction in tenths and a fraction in the hundredths to tell what fraction of the fourth-grade students are boys

Answer 1

Step 1. Gather all of the information.

Out of 100 students, 70 students are girls. This also means that the other 30 students are boys:

--> 70 girls, and 30 boys for every 100 students.

Step 2. Write a fraction in tenths and a fraction in hundredths to tell what fraction of the fourth-grade students are girls.

The fraction in hundredths:

`(70)/(100)`

To find the fraction in tenths, we simplify the previous fraction by dividing both numbers by 10, and the resulting numbers are 7 and 10.

The fraction in tenths:

`(7)/(10)`

Step 3. Write a fraction in tenths and a fraction in the hundredths to tell what fraction of the fourth-grade students are boys.

In this case, we use 30 instead of 70 because now we are talking about the number of boys.

The fraction in hundredths:

`(30)/(100)`

We do the same as we did in step 2 to find the fraction tenths, divide both numbers by 10, the result is 3 and 10.

The fraction in tenths:

`(3)/(10)`

Answer:

Write a fraction in tenths and a fraction in hundredths to tell what fraction of the fourth-grade students are girls

`(7)/(10)\text{ and }(70)/(100)`

Write a fraction in tenths and a fraction in the hundredths to tell what fraction of the fourth-grade students are boys

`(3)/(10)\text{ and }(30)/(100)`
