## 6th Grade Math Problems with Answers

### Solved Examples

**Question 1:**Solve for x, $(x - 1)^\frac{3}{2}$ = 125

**Solution:**

Given $(x - 1)^\frac{3}{2}$ = 125

Factors of 125

125 = 5 * 5 * 5 = 5

=> $(x - 1)^\frac{3}{2}$ = 5

On squaring both side, we have

=> $(x - 1)^{\frac{3}{2} * 2} $ = (5

=> $(x - 1)^3$ = 5

Taking cube root of both sides

=> $((x - 1)^3)^\frac{1}{3}$ = $(5^6)^\frac{1}{3} $

=> x - 1 = 5

=> x - 1 = 25

=> x = 25 + 1

=> x = 26.

Step 1:Step 1:

Factors of 125

125 = 5 * 5 * 5 = 5

^{3}

Step 2:Step 2:

=> $(x - 1)^\frac{3}{2}$ = 5

^{3}On squaring both side, we have

=> $(x - 1)^{\frac{3}{2} * 2} $ = (5

^{3})^{2 }=> $(x - 1)^3$ = 5

^{6}[ (x^{m})^{n}= x^{mn}]^{ }

Step 3:Step 3:

Taking cube root of both sides

=> $((x - 1)^3)^\frac{1}{3}$ = $(5^6)^\frac{1}{3} $

=> x - 1 = 5

^{2}=> x - 1 = 25

=> x = 25 + 1

=> x = 26.

**answer****Question 2:**There were 120 questions on the math exam. Bravo got 65% of them right. How many questions did he get right.

**Solution:**

Let number of questions Bravo got right = x

Total number of the questions in the exam = 120

He got 75 % of the total.

The number of question Brovo got right

=> $\frac{Number\ of question \ Brovo \ got \ right}{Total \ number \ of \ question} = \frac{65}{100}$

=> $\frac{x}{120} = \frac{65}{100}$

=> 100 * x = 65 * 120

=> x = $\frac{65 * 120}{100}$

=> x = $\frac{5 * 13 * 2 * 2 * 2 * 3 * 5}{2 * 2 * 5 * 5}$

=> x = 2 * 3 * 13

=> x = 78

Hence Brovo got 78 questions right.

**Step 1:**Total number of the questions in the exam = 120

He got 75 % of the total.

The number of question Brovo got right

=> $\frac{Number\ of question \ Brovo \ got \ right}{Total \ number \ of \ question} = \frac{65}{100}$

=> $\frac{x}{120} = \frac{65}{100}$

**Step 2:**

Solve for x,**$\frac{x}{120} = \frac{65}{100}$**

=> 100 * x = 65 * 120

=> x = $\frac{65 * 120}{100}$

=> x = $\frac{5 * 13 * 2 * 2 * 2 * 3 * 5}{2 * 2 * 5 * 5}$

=> x = 2 * 3 * 13

=> x = 78

Hence Brovo got 78 questions right.

**answer****Question 3:**Find the area of a circle with a diameter 12 inches and round the answer to the nearest tenth of an inch.(use $\pi$ = 3.14).

**Solution:**

Given:

Diameter of the circle = 12 in.

then radius of the circle = $\frac{12}{2}$ = 6 in

[ Radius = $\frac{Diameter}{2}$ ]

[ Area of circle = $\pi$ r

=> Area of circle = $\pi$ (6)

= 3.14 * 36

Area of circle = 3.14 * 36

= 113. 04

or 113.0(approx)

=> Area of the circle = 113 square inches.

Diameter of the circle = 12 in.

then radius of the circle = $\frac{12}{2}$ = 6 in

[ Radius = $\frac{Diameter}{2}$ ]

Step 1:Step 1:

[ Area of circle = $\pi$ r

^{2}, r = radius ]=> Area of circle = $\pi$ (6)

^{2}= 3.14 * 36

Step 2:Step 2:

Area of circle = 3.14 * 36

= 113. 04

or 113.0(approx)

=> Area of the circle = 113 square inches.
