Question

5*1/5*100; 24/25:6*25; 15/100:3:2; 3/8*7:3

Answer 1

5*1/5*100=100
24/25:6*25=4
15/100:3:2=0,025
3/8*7:3=0,875

Answer 2

Let's solve each of these expressions step by step:

1. $5 \cdot \frac{1}{5} \cdot 100$: First, simplify within the parentheses by multiplying: $5 \cdot \frac{1}{5} = 1$ So, the expression becomes: $1 \cdot 100 = 100$

2. $\frac{24}{25} : 6 \cdot 25$: First, perform the division: $\frac{24}{25} \div 6 = \frac{4}{25}$ Then, multiply by 25: $\frac{4}{25} \cdot 25 = 4$

3. $\frac{15}{100} : 3 : 2$: First, simplify the fraction: $\frac{15}{100} = \frac{3}{20}$ Now, perform the division: $\frac{3}{20} \div 3 = \frac{1}{20}$ Finally, divide by 2: $\frac{1}{20} \div 2 = \frac{1}{40}$

4. $\frac{3}{8} \cdot 7 : 3$: First, perform the multiplication: $\frac{3}{8} \cdot 7 = \frac{21}{8}$ Then, perform the division: $\frac{21}{8} \div 3 = \frac{7}{8}$

So, the results are:

1. (5 \cdot \frac{1}{5} \cdot 100 = 100
2. ( \frac{24}{25} : 6 \cdot 25 = 4
3. ( \frac{15}{100} : 3 : 2 = \frac{1}{40}
4. ( \frac{3}{8} \cdot 7 : 3 = \frac{7}{8}
