Answered by GPT 3.5
To write 19.812 as a fraction, we need to convert the decimal to a fraction. We know that 19 is the whole number part, 812 is the decimal part with three digits. Since there are three digits after the decimal point, we multiply the decimal by 1,000 to get rid of the decimal point.

19.812 * 1,000 = 19,812

So, 19.812 can be written as a fraction as 19,812/1,000.

which is bigger?

a. 8.540 8.504
Answered by GPT 3.5
The number 8.540 is bigger than 8.504.

Both numbers have the same whole number part, which is 8. But when comparing the decimal parts, we see that in 8.540, the digit in the hundredths place is 5 and in 8.504, the digit in the hundredths place is 0.

Since 5 is greater than 0, the number 8.540 is larger than 8.504.

which is bigger

10.5198 or 10.52
Answered by GPT 3.5
To determine which number is larger, we compare the digits in the tenths and hundredths places.

In 10.5198, the digit in the tenths place is 1 and in the hundredths place is 5.
In 10.52, the digit in the tenths place is 1 and in the hundredths place is 2.

Since the digits in the tenths place are the same (1), we compare the digits in the hundredths place. In this case, 5 is greater than 2.

Therefore, 10.5198 is greater than 10.52.

Jennifer earns $760.00 per week. Alex earns 3/4 of what Jennifer earns per week.
How much does Alex earn per week? ____________________

If they both work 40 hr per week, how much do they each make per hour? _________________________________________
Answered by GPT 3.5
To find Alex's earnings per week, we need to multiply Jennifer's earnings by 3/4.

Alex's earnings per week = Jennifer's earnings per week * 3/4 = $760.00 * 3/4 = $570.00.

Now, to find their earnings per hour, we need to divide their weekly earnings by the number of hours worked:

Jennifer's earnings per hour = $760.00 / 40 = $19.00 per hour.
Alex's earnings per hour = $570.00 / 40 = $14.25 per hour.

Olivia's diet allows her 60 grams (g) of fat per day. If she has 1/4 of her total fat grams for breakfast and a hamburger (19.8 g of fat) for lunch, how many grams does she have left for dinner? _______________________________________
Answered by GPT 3.5
To find out how many grams of fat Olivia has left for dinner, we need to subtract the grams of fat from her breakfast and lunch from the total grams of fat she is allowed per day.

Olivia has 1/4 of her total fat grams for breakfast, which is 1/4 * 60 g = 15 g.
She also has 19.8 g of fat from the hamburger for lunch.

So far, she has consumed 15 g + 19.8 g = 34.8 g of fat.

To find out how many grams of fat she has left for dinner, we subtract the fat consumed from the total allowed fat grams:
60 g - 34.8 g = 25.2 g

Therefore, Olivia has 25.2 grams of fat left for dinner.
