Answer 3

Rounding to the Tenths

To round numbers to the tenths place, we look at the digit in the hundredths place. If it is 5 or greater, we round up; if it is less than 5, we round down. Let's apply this rule to the given numbers:

a. 0.27 - The digit in the hundredths place is 7, which is greater than 5. - Rounding up, we get 0.3.

b. 2.82 - The digit in the hundredths place is 8, which is greater than 5. - Rounding up, we get 2.9.

c. 63.77 - The digit in the hundredths place is 7, which is greater than 5. - Rounding up, we get 63.8.

d. 10.97 - The digit in the hundredths place is 7, which is greater than 5. - Rounding up, we get 11.0.

Prices in the Supermarket

Denis saw an advertisement in a supermarket with the following prices:

- Pencils: 34.95 UAH - Markers: 68.25 UAH - Paints: 99.85 UAH

Denis wants to know which items were actually priced significantly less than 100 UAH. Let's compare the prices to see which ones meet this criterion:

- Pencils: 34.95 UAH - The price of pencils is less than 100 UAH, so they are priced significantly less than 100 UAH.

- Markers: 68.25 UAH - The price of markers is less than 100 UAH, so they are priced significantly less than 100 UAH.

- Paints: 99.85 UAH - The price of paints is equal to 100 UAH, so they are not priced significantly less than 100 UAH.

Based on these comparisons, the pencils and markers are the items that were priced significantly less than 100 UAH.
