Answer:
20.8333...
Step-by-step explanation:
1 1/4=5/4
(5/4)/3=x/50
cross product
3*x=(5/4)(50)
3x=250/4
3x=62.5
x=62.5/3
x=20.8333...
First, let's input "a" and "b" into the equation:
(Don't forget to put brackets around the inputted numbers to show you are inputting "a" and "b")
<span>4 ÷ a × b = </span>4 ÷ (444) x (213)
Now we can solve!
= 1.918
= ~ 2
Hope this helps!
