Which equation can be used to solve 3/5 divided by 7/10

Jlenok [28]

Answer:

35/50

Step-by-step explanation:

Here we will show you how to calculate 3/5 divided by 7/10. We will give you the answer in fraction form and in decimal form.

Here is 3/5 divided by 7/10 displayed

3/5 ÷ 7/10

The numbers in 3/5 divided by 7/10 are labeled below:

3 = dividend numerator

5 = dividend denominator

7 = divisor numerator

10 = divisor denominator

To make it a fraction form answer, you multiply the dividend numerator by the divisor denominator to make a new numerator.

Furthermore, you multiply the dividend denominator by the divisor numerator to make a new denominator:

3 x 10/5 x 7 = 30/35

Thus, the answer to 3/5 divided by 7/10 in fraction form is:

30/50

What are the steps to solve for: 1/5(x+5)=1/4(x-3)+1

andrew11 [14]

Step 1. Simplify $\frac{1}{5} (x+5)$ to $\frac{x+5}{5}$

$\frac{x+5}{5} = \frac{1}{4} (x-3)+1$

Step 2. Simplify $\frac{x+5}{5}$ to $1+ \frac{x}{5}$

$1+ \frac{x}{5} = \frac{1}{4} (x-3)+1$

Step 3. Simplify $\frac{1}{4} (x-3)$ to $\frac{x-3}{4}$

$1+ \frac{x}{5} = \frac{x-3}{4} +1$

Step 4. Cancel $1$ on both sides

$\frac{x}{5} = \frac{x-3}{4}$

Step 5. Multiply both sides by $20$ (the LCM of $5,4$ )

$4x=5(x-3)$

Step 6. Expand

$4x=5x-15$

Step 7. Subtract $5x$ from both sides

$4x-5x=-15$

Step 8. Simplify $4x-5x$ to $-x$

$-x=-15$

Step 9. Multiply both sides by $-1$

$x=15$

Done! :) Hope this helps! :)
