Answer:
45.8
Step-by-step explanation:
Say the number Malachy was thinking of is <em>x</em>.
Doubling it gives 2x, which we see also equals 91.6. Set these equal to each other:
2x = 91.6
To solve, we divide both sides by 2 and get x = 45.8, which is our answer.
Numbers 8/9 and 47/70 are between 3/5 and 5/7
Step-by-step explanation:
- Step 1: Find the equivalent decimal expressions of all the given fractions to find which ones are between 3/5 and 5/7
3/5 = 0.6 and 5/7 = 0.71
Option 1 ⇒ 1/2 = 0.5
Option 2 ⇒ 3/7 = 0.43
Option 3 ⇒ 8/9 = 0.89
