Question

Which statement about this product is true? 0.36×(−758)

A.) It is less than −758-758 because multiplying by a number less than 11 gives a smaller number.


B.) It is greater than −4-4 because 0.36×(758)0.36×758 is less than 12×812×8.


C.) It equals −758-758 because 36363636 equals 11, and 11 times any number equals that number.


D.) It equals 00 because 0.360.36 rounded to the nearest whole number is 00, and 00 times any number is 00.

Answer 1

the answer is b

if you do .036 x (-7 5/8) gives you -2.745

Answer 2

B. It is greater than -4 because 0.36*(7 5/8) is less than 1/2 * 8

Explanation:

Given the question:

Which statement about this product is true? 0.36*(-7 5/8)

If you replace the multiplication:

0.36*(7 5/8)

by

1/2*8 = 4

You will get a greater result because 1/2 ( or 0.5) is greater than 0.36 and 8 is greater than (7 5/8). Taking into account that the original multiplication involves a negative number, then:

0.36*(7 5/8) < 1/2*8

0.36*(-7 5/8) > 1/2*(-8) (multiply by a negative number at both sides of the inequality change the sign)

In fact 0.36*(-7 5/8) = -2.745.
