To divide a whole number by a fraction, multiply the whole number by the reciprocal of the fraction. For example, 3 ÷ 1/3 = 3 × 3/1 = 9.

To find the amount in each group, divide the total amount by the number of groups. For example, if Cyril put 1/8 lb of gravel into 6 tanks, the amount in each tank is 1/8 ÷ 6 = 1/48 lbs.

A budget is a plan that outlines expected income and expenses over a certain period. It helps individuals manage their finances.

To calculate the remaining amount after a sale, subtract the sold amount from the original amount. For example, Mr. Anderson had 185 pieces of wood and sold 25, so he has 185 - 25 = 160 pieces left.

The equation is: Number of groups = Total amount ÷ Size of each group. For example, if Mr. Anderson has 160 pieces of wood and each pile has 40 pieces, then p = 160 ÷ 40 = 4 piles.

A balanced budget means that your total income equals your total expenses, so you are not spending more than you earn.

To find the total mileage before a certain distance was driven, subtract the distance driven from the current total mileage. For example, if the car's total mileage is 87,416 miles and it drove 2,718.3 miles last month, then the previous mileage was 87,416 - 2,718.3 = 84,697.7 miles.

The reciprocal of a fraction is obtained by flipping the numerator and denominator. For example, the reciprocal of 1/3 is 3/1.

Understanding fractions in division is important because it allows you to solve problems involving parts of a whole, such as dividing quantities into smaller equal parts.

To determine the maximum amount you can spend, subtract your total expenses from your total income. For example, if Nancy has $50 income and $40 expenses, she can spend $50 - $40 = $10.
