Answer:
1 : 4
Step-by-step explanation:
3.5 : 14 ( divide both parts by 3.5 )
= 1 : 4
I believe here are the necessary steps
<span>- Multiply the numerators together
- Check to see if the product can be simplified
- Multiply the denominators together
Infraction multiplication, we do not have to find a common denominator. And inverse played a role in a division between two fractions, not multiplication per se.</span>
Answer:
5 1/2
Step-by-step explanation:
9 3/5 - 4 1/10
First you need to get common denominator, as we see that we need to get the 5 from the 3/5 to ten, so we multiply 3/5 by 2 on both of the numerator and denominator and you will get 6/10. So the new fraction would be 9 6/10 - 4 1/10 = which would be subtractable. Therefore the answer would be 5 5/10 which equals
5 1/2
AD = AB
AD = 2r+8
AB = 5r-13
we need to find the value of r to find the total length
so 2r+8 = 5r-13
subtract 2r from each side:
8 = 3r -13
add 13 to each side:
21 = 3r
divide both sides by 3
r = 21 / 3 = 7
r=7
now we know r, so replace r with 7 in the equation for AD
AD = 2r+8 = 2(7) +8 = 14 +8 = 22
the answer is D. 22
Answer:
D
Step-by-step explanation:
5 divided by 3 is 1.6666 which is the same as 1 and 2/3
