Question
Which expressions are less than 7/8? Choose all answers that apply:
a) 7/8 x 9/15
b) 7/8 x 3/4
c) 7/8 x 9/9
d) 7/8 x 4/3
Answer:
a) 7/8 x 9/15
b) 7/8 x 3/4
Step-by-step explanation:
We are asked to find which expression are least than 7/8
Solving 7/8 = 0.875
We would evaluate the given option one after the other.
a) 7/8 x 9/15
= 63/120 = 0.525
b) 7/8 x 3/4
= 21/32 = 0.65625
c) 7/8 x 9/9
= 7/8 × 1 = 7/8 = 0.875
d) 7/8 x 4/3
= 7/6 = 1.1666666667
Therefore, from the above calculation, the expressions are less than 7/8 are
option a) a) 7/8 x 9/15 and b) 7/8 x 3/4
Answer:
n = 55/8
Step-by-step explanation:
You can solve it by cross multiplying. Where you multiply the denominator of the fraction on the left side with the numerator on the right side, and vice versa.
11/n = 8/5
n x 8 = 11 x 5
8n = 55
n = 55/8
(or 6.875)
Answer:
1. D 2. B 3. C
Step-by-step explanation:
WARNING: I am not 100% sure about 2.
1. If you simplify the first part of the equation for letter D, you'll realise it is the same equation.
2. It is either B or D. I believe it is B because you would not have to multiply 4 again.
3. The square root of 121 is eleven, the square root of x^2 is x. x=11.
