podryga [215]

Answer:

1/8 of the original sum still remains.

Step-by-step explanation:

If you spend 3/4 of what you have, you have 1/4 left.

Now you spend 1/2 of that 1/4, so basically divide 1/4 by 2. When dividing fractions you can multiply the fraction by the reciprocal of the other fraction.

$\frac{1}{4}$ ÷ $\frac{2}{1}$ = $\frac{1}{4}$ * $\frac{1}{2}$

= 1/8

So I think 1/8 of the original sum still remains.

Hope this helped, please mark brainliest if possible. Have a nice day.

To find the answer, you have to follow the BIDMAS

B-brackets

M-multiplication
A-addition
S-substraction

so in 3-3×6+2 first we have to do the multiplication then addition and finally substraction.

3-3×6+2
=3-18+2
=3-16
=-13

answer=-13
