Answer 1

133, 412500, 500, 1.184, 37.8, 10, 0.6

Explanation:

If we think about how many centimeters are in a meter, we know that

1m = 100cm

Using this, we can see that

20m = 2000cm

Now divide by 15:

2000 ÷ 15 ≈ 133

She can make roughly about 133 ribbons.

To solve the next question, we need to know how many kilometers are in a meter

1km = 0.001m

Let's covert 0.75 into m:

0.75 × 1000 = 750

Now solve for the area:

750 × 550 = 412500

The area of the rectangle is 412500

If he is selling the home for 206,250,000 pesos,

206,250,000 divided by 412500

206,250,000 ÷ 412500 = 500

The price per square meter is 500

If each glass is 148 milliliters, and we need to convert that into liters, we can use the equation:

1L = 1000mL

So converting 148 into liters,

148mL = 0.148L

Now, multiply by 8.

0.148 × 8 = 1.184L

We need to convert 100 Fahrenheit to Celsius.

100 F ≈ 37.8

This is definitely not a normal body temperature.

We can convert grams to kilograms using the equation:

1kg = 1000 g

Converting 2.5kg to g would look like this:

2.5kg = 2500g

250g × 10 = 2500g

We need to buy 10 packs of sugar.

If 120 grams of powdered milk can produce 60 cups of milk, and we need to figure out how many kg can produce the same amount, we use the equation:

1kg = 1000g

Converting 120g to kg would look like this:

120 ÷ 1000 = 0.120

Now, we need to figure out how many times 12 goes into 60.

12 × 5 = 60

Now we multiply 0.120 by 5

0.120 × 5 = 0.6

I hope this helps!
