Пошаговое объяснение:

5 1\4:2=21/4*1/2=21/8=2 5/8

3 1\4:2= =13/4*1/2=13/8=1 5/8

2 1\2:2==5/2*1/2=5/4=1 1/4

Answer 2

To solve each of these expressions, we need to perform the division operation.

1. $5 \frac{1}{4} \div 2$: To divide a mixed fraction by a whole number, we first convert the mixed fraction into an improper fraction and then perform the division. The improper fraction equivalent of $5 \frac{1}{4}$ is $\frac{21}{4}$. $\frac{5\frac{1}{4}}{2} = \frac{21}{4} \div 2 = \frac{21}{4} \times \frac{1}{2} = \frac{21}{8} = 2 \frac{5}{8}$

2. $3 \frac{1}{4} \div 2$: Similarly, convert $3 \frac{1}{4}$ to an improper fraction: $\frac{3\frac{1}{4}}{2} = \frac{13}{4} \div 2 = \frac{13}{4} \times \frac{1}{2} = \frac{13}{8} = 1 \frac{5}{8}$

3. $2 \frac{1}{2} \div 2$: Convert $2 \frac{1}{2}$ to an improper fraction: $\frac{2\frac{1}{2}}{2} = \frac{5}{2} \div 2 = \frac{5}{2} \times \frac{1}{2} = \frac{5}{4} = 1 \frac{1}{4}$

So, the results are: $5 \frac{1}{4} \div 2 = 2 \frac{5}{8}$ $3 \frac{1}{4} \div 2 = 1 \frac{5}{8}$ $2 \frac{1}{2} \div 2 = 1 \frac{1}{4}$
