Step-by-step explanation:
What is 40% of 400?
- Convert the problem to an equation using the percentage formula: P% * X = Y
- P is 40%, X is 400, so the equation is 40% * 400 = Y
- Convert 40% to a decimal by removing the percent sign and dividing by 100:40/100 = 0.4
- Substitute 0.10 for 10% in the equation: 40% * 400 = Y becomes 0.4 * 400 = Y
- Do the math: 0.4 * 400 = 160
- Y = 160
- So 10% of 150 is 160
- Double check your answer with the original question: What is 40% of 400? Multiply 0.4 * 400 = 160
Answer:
12x + 2
Step-by-step explanation:
12 is multiplyed by both the x and the (1/6) since it is outside the equation.
so 12 times x = 12x since we dont know what x is
and 12 times (1/6) = (12/6) = 2
6/7 divided by 12/1 =
6/7 times 1/12=
6/84
