Math topics for grade 7:

Number and Operations

### Solved Examples

**Question 1: **Simplify 12 x 45 $\div$(12 - 7) + 4.

** Solution: **

Given, 12 x 45 $\div$(12 - 7) + 4

12 x 45 $\div$(12 - 7) + 4 = 12 x 45 $\div$5 + 4

= 12 x 45 x $\frac{1}{5}$ + 4

= 12 x 9 + 4

= 108 + 4

= 112

=> 12 x 45 $\div$(12 - 7) + 4 = 112

**Question 2: **Solve the proportion for x and check your answer.

$\frac{x}{35} = \frac{3}{7}$

** Solution: **

Given, $\frac{x}{35} = \frac{3}{7}$

$\frac{x}{35} = \frac{3}{7}$

=> 7x = 3 $\times$ 35

=> x = $\frac{3 \times 35}{7}$

=> x = 15

Check:

LHS = $\frac{x}{35}$

= $\frac{15}{35}$

= $\frac{3 \times 5}{5 \times 7}$

= $\frac{3}{7}$

= RHS

**Question 3: **Area of a circular table is 154 square feet. What is the radius and diameter of the table.

** Solution: **

Given

Area of the circular table (A) = 154 square feet

Let 'r' be the radius and 'd' be the diameter of the circle

Use the formula,

A = ∏ r^{2}

=> 154 = $\frac{22}{7}$ * r^{2}

=> 154 x $\frac{7}{22}$ = r^{2
} => 7 x 7 = r^{2}

=> r = 7

and d = 2 r = 2 x 7 = 14

=> Radius of circular table = 7 feet

and diameter = 14 feet.

Below are some 7th grade practice problems. Students can follow these and check their understanding level.

### Practice Problems

**Question 1: **Jiany needs to type an article that will be 20 pages long. Each page
contains about 100 words. If Jiany can type 50 words per minute, how
many minutes will it take him to complete the article? (Answer: 40 mins)

**Question 2: **What would be the compound interest accrued on an amount of 7400 dollars at the rate of 13% at the end of 2 years? (Answer: C.I. = 2132.87 dollars)

Given, 12 x 45 $\div$(12 - 7) + 4

12 x 45 $\div$(12 - 7) + 4 = 12 x 45 $\div$5 + 4

= 12 x 45 x $\frac{1}{5}$ + 4

= 12 x 9 + 4

= 108 + 4

= 112

=> 12 x 45 $\div$(12 - 7) + 4 = 112

$\frac{x}{35} = \frac{3}{7}$

Given, $\frac{x}{35} = \frac{3}{7}$

$\frac{x}{35} = \frac{3}{7}$

=> 7x = 3 $\times$ 35

=> x = $\frac{3 \times 35}{7}$

=> x = 15

Check:

LHS = $\frac{x}{35}$

= $\frac{15}{35}$

= $\frac{3 \times 5}{5 \times 7}$

= $\frac{3}{7}$

= RHS

Given

Area of the circular table (A) = 154 square feet

Let 'r' be the radius and 'd' be the diameter of the circle

Use the formula,

A = ∏ r

=> 154 = $\frac{22}{7}$ * r

=> 154 x $\frac{7}{22}$ = r

=> r = 7

and d = 2 r = 2 x 7 = 14

=> Radius of circular table = 7 feet

and diameter = 14 feet.
