The answer is b.
15/20. multiply 3/4 by 5 on both the top and bottom,, the result is 15/20. Once you have 15/20 you take the other fraction (2/5) and multiply both the top and bottom by 4. You should end up with 8/20 now that both fractions have the same denominator you can subtract them. Once you do so the denominator will stay the same except the numerator you end up with 7/20 with this fraction you can add 8/20 when they are added together you should get 15/20.

Which property is used in the statement? <br> If z=3+1, then 3+1=z
inessss [21]
This is the symmetric property of equality, and in a more general form it can be written  as: if a=b then b=a.

<span>This  is not to be confused with communicative property,  which says that the order doesn't  matter in some operations, such as addition, and can be written as a+b=b+a</span>

A car is traveling at a speed of 108 kilometers per hour. What is the cars speed in kilometers per minute? How many kilometers w
cluponka [151]

The distance travelled by the car will be 3.6km in 2 minutes.

<u>Explanation:</u>

Given:

Speed, s = 108 km/hr

s in km/min = ?

1 hr = 60 min

So,

108 km/hr = \frac{108}{60} km/min

                 = 1.8 km/min

time, t = 2 min

Distance, d = ?

We know:

distance = speed X time

d = 1.8 X 2\\\\d = 3.6km

Therefore, the distance travelled by the car will be 3.6km in 2 minutes.
