What is the greatest measure of length? A. 5,000 meters B. 6,000 centimeters C. 30,000 millimeters D. 1 kilometer
Bess [88]

Answer: A. 5,000 meters

Step-by-step explanation:

Starting with the smallest unit which is option C. There are 10 millimeters in one centimetre. Option c in centimeters is:

= 30,000 / 10

= 3,000 meters.

Option c is smaller than B and so is incorrect.

A meter is 100 centimeters. Option b in meters is;

= 6,000 / 100

= 60 meters

This is less than option A so is incorrect.

A kilometer is 1,000 meters so option A in meters is:

= 5,000 / 1,000

= 5 kilometers

This is higher than option d so option A is correct.

Can someone help me please

<u>Answer:</u>

Multiply \frac { 3 } { 4 } by 8.

<u>Step-by-step explanation:</u>

We are given the following expression and we are to find its quotient:

\frac { 3 } { 4 } ÷ \frac { 1 } { 8 }

This can also be written as:

\frac{\frac{3}{4}}{\frac{1}{8} }

Since the two fractions are being divided so to change this division sign into a multiplication sign, we will take the reciprocal of the fraction in the denominator and multiply 3/4 by 8.

\frac{3}{4} \times 8 = 6
