1 answer

Certainly! Let's use each of the four operations—addition, subtraction, multiplication, and division—to set up and solve some real-world problems.

Addition Problem

Scenario: Sarah has 275 stickers, and her friend gives her 148 more stickers. How many stickers does Sarah have now?

Solution: \[ 275 + 148 = 423 \]

Sarah now has 423 stickers.


Subtraction Problem

Scenario: Carlos had 520 marbles. He gave away 178 marbles to his friends. How many marbles does Carlos have left?

Solution: \[ 520 - 178 = 342 \]

Carlos has 342 marbles left.


Multiplication Problem

Scenario: A box contains 24 chocolates. If there are 15 boxes, how many chocolates are there in total?

Solution: \[ 24 \times 15 = 360 \]

There are 360 chocolates in total.


Division Problem

Scenario: A farmer has 840 apples and wants to pack them into boxes that can each hold 28 apples. How many boxes can he fill?

Solution: \[ 840 \div 28 = 30 \]

The farmer can fill 30 boxes.
