Use proportion to find the whole 75 is 15% of what number
Iteru [2.4K]

Answer:

500

Step-by-step explanation:

15% * x = 75

(15/100) * x = 75           Multiply both sides by 100/15

(15/100)*(100/15) = 75 * 100/15

x = 7500/15

x = 500

Answer 500

Proportion

15/100 = 75 / x             Cross multiply

15x = 100*75                Combine the right

15x = 7500                   Divide 15

15x/15 = 7500/15

x = 500

How many kilograms is a rice packet that weighs 750 g?<br> (Please answer quick!)
RideAnS [48]

Answer:

0.750 kg

Step-by-step explanation:

Hi there ,

As you know 1 kg = 1000g

So when we convert g to kg then we divide the given value of grams by 1000.

So in this case we have 750 grams, changing it we have :

\frac{750}{1000}

Since there are 3 zeroes in 1000 we move the decimal point by 3 places to the left leaving the answer as : 0.750 kg or \frac{750}{1000} kg

Please mark me as brainliest if you found the above answer helpful
