Which of the following is a true statement?

B; 2/3 < 5/7

Step-by-step explanation:

Find a common denominator:

A common denominator is 21. Multiply the denominators by the number you need to get to 21. The common denominator would be 7 for 2/3 and 3 for 5/7.

x 7=  14/21

x 3 = 15/21

The statement would be 14/21 < 15/21 which is true. Therefore, your answer is B; the second statement from the top.

3/4 ÷ 3/4

step-by-step explanation:

basically divide any proper fraction with itself to fit the criteria.

so if we are using 3/4, then:

3/4 ÷ 3/4 = 1

so 1 is the quotient.

and the numerators for both these fractions is 3.   and if we divide the numerators:

3 ÷ 3 = 1

we see that quotient is equal to our original quotient as well.

the answer would be 1 1/72

step-by-step explanation:

you can rewrite the equation by separating the parts and then solving individually:

10-9=1

1/8 - 1/9=

find l c d and then combine:

1 1/72
