To simplify<span> a </span>fraction<span>, both the numerator and denominator must be divided by the </span>same number<span>. This method is also called canceling </span>down<span> or reducing the </span>fraction<span>. </span>
Answer:
(a) This is just `8` people being arranged in a row: `8! = 40,320` (b) Regard the `2` boys as one "unit" and so there are `7` "units" to arrange. This can be done `7! = 5040` ways. The boys can be arranged in `2! = 2` ways, so the required answer is `7! × 2! = 10,080` (c) There are only `2` possibilities: the boys are together or they are not.
Step-by-step explanation:
The nearest whole number is <span><span>8</span></span>
When we are looking at rounding, we round to the number that our fraction or decimal is located. So, since we are rounding to the nearest whole number, given our original mixed number (
) our answer will be either 7 or 8.
We can change
to a decimal to equal 7.8 by multiplying both our denominator and our numerator by 2 since 5 * 2 =10, which would change our fraction to
which is the same thing as .8
If we look at 7.8 and want to know if it is closer to 8 or 7, we just remember that when rounding, if it is 5 or above, you round up, anything else, you leave the number in front of it like it is. .8 is above 5 so we round 7 to the whole number 8. So, our answer is 8
Thank you for your question! I hope this helped! Have an amazing day and feel free to let me know if I can help you further! :D
Same thing. 22^2+b^2=33^2
484+b^2=1089
b^2=605
b=24.60
35.9002 that’s the answer
