Answer:

0.125

Step-by-step explanation:

Step 1: Find a number such that we can multiply by the denominator of the fraction to make it 10 or 100 or 1000 and so on

Step 2: Multiply both numerator and denominator by that number to convert it into it's equivalent fraction.

Step 3. Then write down just the numerator, putting the decimal point in the correct place i.e., one space from the right hand side for every zero in the denominator

1/8 = (1×125)/(8×125) = 125/1000 = 0.125

Thus, as a decimal 1/8 is 0.125

Which statement compares the two numbers correctly?

slamgirl [31]

Answer:

Step-by-step explanation:

So, we have-

(6 x .1) + (3 x .01) + (2 x .001)

So, we will solve inside of the parenthesis first.

6 x .1 = .6

So, we got that settled next-

3 x .01 = .03

We got that settled last-

2 x .001 = .002

Lastly, we add them all.

.6 + .03 + .002 = .632

Now we compare.

.632 > .629

So, there is your answer!

Hope this helps!

After 5 tests Dara's average score was 88 what score must she average on the next two tests to have a seven-test average of 90?

Tomtit [17]

After 5 tests, her average was 88. To have a seven-test average of 90, the total must be:

$90 \times 7 = 630$

Her average after 5 tests was 88. Her total score on the 5 tests is:

$88 \times 5 = 440$

Subtract:

$630-440 = 190$

Find the average by dividing by 2:

$190 \div 2 = 95$

Her average must be 95
