A:
Answer: "Yes." ______________________________________________________ Explanation: ______________________________________________________ " Yes; since: "80/100" m = "8/10" m = "0.8" m . ______________________________________________________ Note: Cancel out a "zero" from BOTH the "80" (in the numerator) and the "100" (in the denominator); to get: "80/100" = "8/10" .
This is the same as: "80/100" = "(80÷10) / (100 ÷10)" = "8/10". ___________________________________________________ Note that: "8/10" can be written as the decimal equivalent: "0.8" . ___________________________________________________ As such: "80/100" m = "8/10" m = "0.8" m . ___________________________________________________
