−2 1/4=r−4/5 What is r?

Mathematics

dmitriy555 [2]3 years ago

Answer:

r = -29/20 or r = -1.45

Step-by-step explanation:

I believe you are saying that the equation is -2 1/4 = r - 4/5. If so, then I would solve it in this way:

-2 1/4 = r - 4/5

-9/4 = r - 4/5

-9/4 (20) = r (20) - 4/5 (20)

-45 = 20r - 16

20r = -29

r = -29/20

r = -1.45

Check:

-2 1/4 = r - 4/5

-9/4 = r - 4/5

-2.25 = r - 0.8

-2.25 = -1.45 - 0.8

-2.25 = -2.25

-9/4 = -9/4

NeTakaya

Answer:

The required number of bowls are 5.  

Step-by-step explanation:

Given : A sugar bowl holds 237 grams. You have a one kilogram bag of sugar.

To find : Estimate how many bowls of sugar you can fill from the bag?

Solution :

1 bowl can hold 237 gram of sugar.

We have, 1 kg of sugar or 1000 gram of sugar.                

According to question,

237 gram of sugar can hold in 1 bowl.

So, 1 gram of sugar can hold in \frac{1}{237} bowl.

1000 gram of sugar can hold in \frac{1000}{237} bowl.      

1000 gram of sugar can hold in 4.21 bowl.  

Which means, The required number of bowls are 5.

As 4 bowls have 237\times 4=948 grams of sugar.

Sugar left is 1000-948=52 grams

That 52 grams is filled into 5th bowl.
