WILL MARK BRAINLIEST guess who's back.. lol please don't let this be copied off the internet cause I can look it up and know... I just don't know how to explain this lol. . .

Explain how to use estimation to help find the product of two decimals. Give an example with both estimated and actual answers.

Estimating to the nearest whole number can help us with quicker math, and estimating with decimals will give us a answer in the area.

Ex.) 5.9x8.2 can be estimated to 6x8=48 5.9x8.2=48.38

The answers are approximately in the same range.

percentage - 25%

probability - 0.25

we know,

total amount of students in class = 20

total boys = 10

total girls = 10

no of girls who wear glasses = 10/2 = 5

probability of choosing a girl with glasses is =

number of girls wearing glasses/total number of students in the class = 5/20

thus, percentage of selecting a girl wearing glasses will be

= 5/20 × 100

= 5 × 5

25%

therefore,

probability will be 0.25

happy to

pls mark as brainliest

7.25

step-by-step explanation:

we know that 7 equals to 7.0. we also know that 1/4=0.25. so we can add the two together and we get 7.25
