Solve Multi-Step Word Problems Involving Addition, Subtraction, Multiplication, And Division

Perform addition and subtraction of decimal numbers within seven places (without regrouping and with it), multiplication of numbers from third place at most, division of numbers from four places at most by numbers from two places at most, and use them to solve mathematical problems.

Solve multi-step mathematical problems involving real-life applications on the four operations, and explain their solutions.

Mathematical problems involving at least three steps include practical applications of the four operations on decimal fractions and their interpretation.

What is the sum of the apples Mohammed and Khaled ate in simplest form if Mohammed ate 1 apple and Khaled ate 3 apples?

An art teacher had 237 colored pencils left over from last year. This year, he bought 26 boxes of colored pencils that had 16 pencils in each. He also bought 15 boxes that had 54 pencils in each. Finally, when he was sorting the pencils, 19 rolled under the cabinet and were lost.

Solve the following equation to determine c, the number of colored pencils the art teacher has now.

c = 237 + [ (26 ∙ 16) + (15 ∙ 54) ] – 19

Jay mows lawns and washes cars to earn money. • He earns $8 for each lawn he mows. • He earns $5 for each car he washes. • On Friday, he mowed 3 lawns and washed 3 cars. • On Saturday, he spent $15 of the money he earned. Which expression shows the amount of money Jay had left?

• (3 × 8 + 5) – 15

• 3 × (8 + 5) – 15

• (3 + 8 + 5) – 15

• (8 + 5) – 15 × 3

18 A family spent $93 at a carnival. • They spent $18 on tickets to the carnival and $36 on food. • They spent the rest of the money on games. Which equation can be used to find g, the amount of money in dollars the family spent on games?

• F 93 = g + 36 − 18

• G 93 = 18 + 36 − g

• H 93 = 36 − 18 − g

• J 93 = g + 36 + 18
