It’s D
the reason why is because the multiplier must be between 1 and 10
(
1
≤
x
≤
10
)
so first more your decimal there which you get:
2.34
then just count how many numbers the decimal jumped, if the decimal moved left the exponent is positive and if it moved right, as in your number, the exponent is negative
yours moved 3
There are 42 students and 30 slices of pizza so 42-30=12 so you would need another extra large pizza to feed the whole class.
Hope this helps!
The ratios 84/105 and 128/160 are proportional
<u>Solution:</u>
Given, two ratios are
and 
We have to give two different reasons to support the answer.
<em><u>Reason 1:</u></em>
Now, we know that, numerators and denominators should be proportional to be two fractions in proportion.

So numerators and denominators are in proportion, then given two fractions are proportion.
<em><u>Reason 2:</u></em>
Now, values of two fractions must be equal:

So, values of two fractions are equal, then they are in proportion.
Hence, the given two fractions are in proportion.
You can divide 1/2 by 1/4
that'll leave you with 1/8, which is smaller than 1/4
