If x is equal to 49.5 percent of 11/23 of 0.996, then
A) 0.20 < x < 0.25
B) 0.25 < x < 0.30
C) 0.30 < x < 0.35
D) 0.35 < x < 0.40
E) 0.40 < x < 0.45
Given: x = 49.5 percent of 11/23 of 0.996 In other words, x = (49.5/100)(11/23)(0.996)
Notice that 49.5/100 is a little bit less than 0.5 And 11/23 is a bit less than 0.5. Aside: we know this because 11/22 = 0.5, so 11/23 is a bit less than 0.5 And 0.996 is a bit less than 1
So, x = (little bit less than 0.5)(bit less than 0.5)(a bit less than 1) We know that (0.5)(0.5)(1) = 0.25 So, (little bit less than 0.5)(bit less than 0.5)(a bit less than 1) = a bit less than 0.25
If x is equal to 49.5 percent of \(\frac{11}{23}\) of 0.996, then
A) 0.20 < x < 0.25
B) 0.25 < x < 0.30
C) 0.30 < x < 0.35
D) 0.35 < x < 0.40
E) 0.40 < x < 0.45
We can solve this problem through estimation.
x = 0.495 * 11/23 * 0.996 ≈ 0.5 * 0.5 * 1 = 0.25
We see that x is approximately 0.25; however, since the actual numbers are less than their respective estimated numbers, the actual product is less than 0.25.
