What is the product in lowest terms?-6/11 times 3/4

A.-9/22

B.-6/13

C.9/22

D.6/13

Answers

In multiplying fractions, both numerators are multiplied while both denominators are multiplied. The product of the numerators is the new numerator, and the product of the denominators is the new denominator too.

Given: -6/11 and 3/4

Multiplying the fractions:
-6/11 * 3/4 = (-6 * 3) / (11 * 4)

-18 / 44

However this isn't the final form. The numbers -18 and 44 can still be reduced to lowest terms by dividing both numbers with a common factor. In this case, both of the numbers can be divided by 2, giving us:

(-18/2) / (44/2) = -9 / 22

Therefore the equation is lowest terms is equal to A. -9 / 22

Answer:

The answer is A

What is the mean of the following data values?53, 71, 89, 10, 87

A. 62
B. 71
C. 82
D. 51

Answers

Answer:

Mean of the given data = 62

Step-by-step explanation:

53, 71, 89, 10, 87

To find mean of the given data values

We add all the numbers and divide by the number of datas

We are given with 5 numbers

LEts add all the numbers

53 +71+ 89+ 10+87= 310

Mean = $(sum of numbers )/(number of data)$

= $(310)/(5)$ = 62

A. 62. If you add up all of the numbers, you get 310, then take this number and divide it by 5. you divide it by five because there are five numbers given.
