Given, 5 8 × 4 15 To multiply two fractions, we need to multiply both the numerators and both the denominators. Thus, we get 5 8 × 4 15 = 5 × 4 8 × 15 = 20 120 Here, 20 120 can be represented in to the simplest form. Thus, 20 ÷ 20 120 ÷ 20 = 1 6 Therefore, the product of the given fraction in simplified form is 1 6 .

Multiply the given fraction. 4 12 × 3 5

Given, 4 12 × 3 5 To multiply two fractions, we need to multiply both the numerators and both the denominators. Thus, we get 4 12 × 3 5 = 4 × 3 12 × 5 = 12 60 Here, 12 60 can be represented in to the simplest form. Thus, 12 ÷ 12 60 ÷ 12 = 1 5 Therefore, the product of the given fraction in simplified form is 1 5 .

Multiply the given fraction. 2 3 × 9 14

Given, 2 3 × 9 14 To multiply two fractions, we need to multiply both the numerators and both the denominators. Thus, we get 2 3 × 9 14 = 2 × 9 3 × 14 = 18 42 Here, 18 42 can be represented in to the simplest form. Thus, 18 ÷ 6 42 ÷ 6 = 3 7 Therefore, the product of the given fraction in simplified form is 3 7 .

According to a survey at the time of writing, approximately 21 25 of American teenagers own a cell phone. Of these teenagers, 1 3 of them use messaging apps. What fraction of American teenagers does this represent?

Given, The fraction of American teenagers own a cell phone = 21 25 Fraction of them use messaging apps = 1 3 1 3 of 21 25 American teenagers use messaging apps. To multiply two fractions, we need to multiply both the numerators and both the denominators. Thus, we get 1 3 × 21 25 = 1 × 21 3 × 25 = 21 75 Here, 21 75 can be represented in to the simplest form. Thus, 21 ÷ 3 75 ÷ 3 = 7 25 Therefore, the required fraction is 7 25 .

According to a survey at the time of writing, approximately 21 25 of American teenagers own a cell phone. Of the teenage cell phone owners, 1 10 of them hardly ever use their phone to make or receive calls. What fraction of American teens does this represent?

Given, The fraction of American teenagers own a cell phone = 21 25 Fraction of them use their phone to make or receive calls = 1 10 1 10 of 21 25 American teenagers use messaging apps. To multiply two fractions, we need to multiply both the numerators and both the denominators. Thus, we get 1 10 × 21 25 = 1 × 21 10 × 25 = 21 250 Therefore, the required fraction is 21 250 .

According to a survey at the time of writing, approximately 21 25 of American teenagers own a cell phone. Of these teenagers, 5 7 of them say they use one or more social network sites. What fraction of American teenagers does this represent?

Given, The fraction of American teenagers own a cell phone = 21 25 Fraction of them use use one or more social network sites = 5 7 5 7 of 21 25 American teenagers use messaging apps. To multiply two fractions, we need to multiply both the numerators and both the denominators. Thus, we get 5 7 × 21 25 = 5 × 21 7 × 25 = 105 175 Here, 105 175 can be represented in to the simplest form. Thus, 105 ÷ 5 175 ÷ 5 = 21 35 Therefore, the required fraction is 21 35 .
