"Number of Stamps" Using Equations to Solve Problems PPT Courseware 2

How many stamps does each brother and sister have? Try to solve it using equations.

Number of stamps for sister = number of stamps for brother × 3

Number of stamps for brother + number of stamps for sister = 180

1. Write the equivalent relationship based on the information in the following questions, and then make equations to solve the problem.

⑴How many centimeters are the length and width of this painting?

⑵How many white keys and black keys are there?

2. Solve the equation.

3. Mom’s age is 3 times and 4 years older than Xiaoli’s. Mom is 37 years old. How old is Xiaoli this year? Solve problems using equations.

As shown in the picture, the perimeter of the square is 5 cm longer than the perimeter of the equilateral triangle. What are the perimeters of the square and the triangle in centimeters?

If they are both in the vigorous growth stage, the bamboo will start to be 32cm tall and the bell fungus will be 0.5cm tall. How long will it take for the bell fungus to reach the height of bamboo? Let’s talk about the equivalence relationship first, and then solve it by making equations.
