Question

relating percents, decimals, and fractions
the hundred grid below represents the number of students out of
100 surveyed that ride the bus to school. write this number as a percent,
a decimal, and a fraction in simplest form by answering 1 to 7.

1. how many students were surveyed?

1. how many students ride the bus out of 100?

1. what percent of the students surveyed ride the bus?

1. write a decimal to represent the shaded

part of the hundred grid.

1. what fraction of the hundred grid is shaded?

1. write the fraction from item 5 in simplest form.

1. the percent, decimal, and fraction forms are all

equal. use one of each form to fill in the blanks.

the same survey of 100 students found that 32% walk to school. write this
percent as a decimal and a fraction in simplest form by answering 8 to 10.

1. to change a percent to a decimal, remove the percent

sign and move the decimal point two places to the left.
what decimal is equal to 32%?

1. to change a percent to a fraction, remove the percent

sign and write the number over a denominator of 100.
what fraction is equal to 32%?

1. write the fraction from item 9 in simplest form.

Explanation:

Question 1

Step1: Identify the total surveyed

The problem states "out of 100 surveyed", so the number of students surveyed is 100.

Step1: Count shaded grid squares

Looking at the hundred grid, the shaded part (students riding bus) has 35 squares (assuming the shaded grid is 5x7 or similar, totaling 35). So out of 100, 35 ride the bus.

Step1: Percent from shaded grid

Since percent is "per 100", the number of students riding bus out of 100 is the percent. From Q2, it's 35, so 35%.

Answer:

100
