How do u work this out and what's the answer
I am Lyosha [343]
1) you would need to turn both fractions so they have a common denominator, that would be 2 2/4 and 3/4
2) then subtract : 2 2/4 - 3/4, and you would subtract numerators and the whole number, but you keep the denominator the same. However, you cannot subtract 2 and 3 in this case, so you need to change 2 2/4 to 1 5/4 (they are still equivalent)
3) 1 5/4 - 3/4 = 1 2/4, which simplified version is 1 1/2
Therefore, the answer is 1 and 1/2

6. Michael Johnson holds the Olympic record for the men's 400m race at 43 seconds. His
vlada-n [284]

The difference between both unit rates rounded off to the nearest tenth is: 0.4 meters per second

Step-by-step explanation:

We have to calculate his unit rate for both type of races

So,

<u>Unit rate for 400m race:</u>

Distance = 400m

Time = 43 sec

Unit\ rate = U_1= \frac{Distance}{Time}\\=\frac{400}{43}\\=9.30\ meters\ per\ second

<u>Unit rate for 300m Race:</u>

Distance = 300m

Time = 31 sec

Unit\ Rate= U_2=\frac{300}{31}\\=9.68\ meters\ per\ second

The difference between both unit rates is:

U_2-U_1 = 9.68-9.30\\=0.38 => 0.4\ meters\ per\ sec

Hence,

The difference between both unit rates rounded off to the nearest tenth is: 0.4 meters per second
