Question

Divide the sum of 3 by 7 and -5 by 14 by minus 2 by 4

Answer 1

Answer -

• The required number is -1/7.

What to do -

• Divide the sum of 3/7 and -5/14 by -2/4.

Step-by-step explanation -

• Here, we are asked to divide the sum of 3/7 and -5/14 by -2/4. For this, we will first find the sum of 37 and -5/14. Then we will divide the number so obtained by -2/4 to get our answer.

Sum of 3/7 and -5/14 -

$\hookrightarrow\dfrac{3}{7} + \dfrac{ - 5}{ \: 14}$

$\hookrightarrow\dfrac{(3 \times 2) + ( - 5 \times 1)}{14}$

$\hookrightarrow\dfrac{6 + ( - 5)}{14}$

$\hookrightarrow \dfrac{6 - 5}{14}$

$\hookrightarrow\dfrac{1}{14}$

-----------------------------------------------------------

• The sum of 3/7 and -5/14 is 1/14. So let's divide this number by -2/4 now!

Dividing the numbers -

$\rightarrow \dfrac{1}{14} \div \dfrac{ - 2}{ \: \: \: 4}$

$\rightarrow\dfrac{1}{14} \times \dfrac{ \: \: \: \: 4}{ - 2}$

$\rightarrow\dfrac{1}{7} \times \dfrac{ \: \: \: \: 1}{ - 1}$

$\rightarrow\dfrac{ \: \: \: \: 1}{ - 7}$

$\rightarrow\dfrac{ - 1}{ \: \: 7}$

Hence -

• The required number is -1/7.

♧♧To prove :-

• Dividing the given sum

♧♧Explanation :-

1. sum of 3/7 and -5/14

• 3/7+(-5/+14)

• 6+(-5)/+14

• 6-5/14

• 1/14.

♧♧♧Let divide it by the number , -2 /4.

1. 1/14÷(-2/4)

• 1/14 ×4/2
• 1/7×1/-1
• 1/-7

• -1/7.

Therefore, required number is -1/7.
