Answer:
30
Step-by-step explanation:
there's a few different ways of solving this:
1)
3/4 = 0.75
0.75 * 40
30
2)
divide 40 by 4 and then multiply by 3
40/4
10
10 * 3
30
3)
[tex]\frac{3}{4} *\frac{40}{1}[/tex]
the 4 and 40 cancel out
[tex]\frac{3}{1}* \frac{10}{1}[/tex]
3 * 10 = 30
[tex]\frac{30}{1}[/tex] = 30
