Which transformations preserve the original quotient? Select all that apply.

Explication

The equal scalings 7.5 ÷ 0.3 to 75 ÷ 3, 4.2 ÷ 0.07 to 420 ÷ 7, and 0.64 ÷ 0.8 to 6.4 ÷ 8 all preserve their quotients. Changing 3.6 ÷ 0.9 to 0.36 ÷ 9 scales the dividend down and the divisor up, so it changes the quotient by a factor of one hundred.
