1.25 * 18 / 20.
The order of operations is:
P (parenthesis)
E (exponents)
M (multiplication) / D (division) --> order for these two is left to right
A (addition) / S (subtraction) --> order for these two is also left to right
So we would do 1.25 * 18 first.
1.25 * 18 = 22.5
Now we will do 22.5 / 20 = 1.125
1.25 x 18 / 20 = 1.125

4 times 4.5 is 18. The opposite of multiplication is division, therefore 18 divided by 4 is 4.5. Also, 4 times 4 is 16 and 4 times 5 is 20. Halfway between 4 and 5 is 4.5 and halfway between 16 and 20 is 18..
0.9

It goes in 18 times.
125 cannot be divided by 20 or 4.
18 divided 20 = 0.9
18.3
20
4 times 4.5 is 18. The opposite of multiplication is division, therefore 18 divided by 4 is 4.5. Also, 4 times 4 is 16 and 4 times 5 is 20. Halfway between 4 and 5 is 4.5 and halfway between 16 and 20 is 18..
5*4=20 20/2=10 10+8=18 18
0.9
because 125 ≠ 20.100 ÷ 80%= 100 ÷ 0.8= 125100 * 20%= 100 * 0.20= 20
The answer is 18 because 90 divided by 5 is 18.
