Work out 12+8÷(9-5) 0.018÷0.06 Express as single fraction 5/7÷2/5

Anettt [7]

Step-by-step explanation:

I don't know if the first set of numbers is all in one set, but I'll do my best to give you an answer.

Really all you need to do is use PEMDAS for the first question.

(Parentheses, exponents, multiply, divide, add, subtract. In that order)

$1 2 + 8 \div (9 - 5) \\ 12 + 8 \div 4 \\ 12 + 2 \\ 14$

Then to simplify that fraction next to it, notice that 0.018 is 3x 0.06.

that's a 3:1 ratio, so it ends up simplifying to this:

$\frac{3}{1}$

Lastly, to solve the division of that fraction. If you divide by a fraction, you multiply whatever it's dividing by its inverse.

So...

$\frac{5}{7} \div \frac{2}{5} \\ \frac{5}{7} \times \frac{5}{2} \\ \frac{25}{14}$

4000÷10×2+4-8 rounded to the nearest ten

Vladimir79 [104]

You would follow the order of operations
Parentheses
Exponents
Multiply/Divide
Add/Subtract

if it is multiply or divide, go from left to right. do the same if it is addition or subtraction

4000/10x2+4-8

first, do 4000/10

400x2+4-8

then do 400x2

800+4-8

then do 800+4

804-8

796
rounding to the nearest tens would make it 800
because 9 rounded up is 10
