What is rounding?

Back

Rounding is the process of adjusting the digits of a number to make it simpler while keeping its value close to what it was. For example, rounding 0.8637 to the nearest hundredth gives 0.86.

Front

How do you round a number to the nearest hundredth?

Back

To round a number to the nearest hundredth, look at the digit in the thousandths place. If it is 5 or greater, increase the hundredths place by 1. If it is less than 5, keep the hundredths place the same.

Front

What is a fraction?

Back

A fraction represents a part of a whole and consists of a numerator (top number) and a denominator (bottom number). For example, 1/4 means one part out of four equal parts.

Front

How do you calculate the number of days worked given a fraction of days?

Back

To find the number of days worked, multiply the total number of days by the fraction. For example, in a 28-day period, if Carole worked 1/4 of the days, she worked 28 * (1/4) = 7 days.

Front

What is the process to find the total number of days not worked?

Back

To find the total number of days not worked, multiply the total number of days by the fraction of days not worked. For example, if Carole did not work 1/14 of the days in a 28-day period, she did not work 28 * (1/14) = 2 days.

Front

What is addition?

Back

Addition is a mathematical operation that combines two or more numbers to get a total. For example, 1,582 + 761 = 2,343.

Front

What is a percentage?

Back

A percentage is a way of expressing a number as a fraction of 100. For example, 60% means 60 out of 100.

Front

How do you find a number when given a percentage of it?

Back

To find a number when given a percentage, divide the percentage value by the percentage rate (in decimal form). For example, if 60% of a number is 30, the number is 30 / 0.6 = 50.

Front

What is a batch in cooking?

Back

A batch refers to a specific quantity of food prepared at one time. For example, if each batch of cookies uses 3 eggs, and you have 20 eggs, you can make 20 / 3 = 6 batches.

Front

How do you determine the maximum number of batches you can make?

Back

To determine the maximum number of batches, divide the total number of ingredients by the amount needed for one batch. For example, with 20 eggs and needing 3 eggs per batch, you can make 20 / 3 = 6 batches.
