Oxana [17]

Answer:

1

Step-by-step explanation:

$\huge {625}^{ \frac{3}{8} } \times {5}^{ \frac{1}{2} } \div 25 \\ \\ = \huge {( {5}^{4})}^{ \frac{3}{8} } \times {5}^{ \frac{1}{2} } \div {5}^{2} \\ \\ = \huge{5}^{ \cancel4 \times \frac{3}{ \cancel8 \: \: \red{ \bold 2}} } \times {5}^{ \frac{1}{2} } \div {5}^{2} \\ \\ \huge= {5}^{ \frac{3}{2} } \times {5}^{ \frac{1}{2} } \div {5}^{2} \\ \\ \huge= {5}^{ \frac{3}{2} + \frac{1}{2}} \div {5}^{2} \\ \\ \huge= {5}^{ \frac{4}{2} } \div {5}^{2} \\ \\ \huge= {5}^{ 2 } \div {5}^{2} \\ \\ \huge= {5}^{ 2 - 2 } \\ \\ \huge= {5}^{ 0 } \\ \\ \huge= 1$

In a fishing competition Johannes and Peter together caught 48 fish.

Alenkasestr [34]

John caught 18 fishes and Peter caught 30 fishes.

Step-by-step explanation:

Let,

Fishes caught by John = x

Fishes caught by peter = y

Total fishes caught = 48

According to given statement;

x+y=48 Eqn 1

x= $\frac{3}{5}y$ Eqn 2

Putting Eqn 2 in Eqn 1;

$\frac{3}{5}y+y=48$

Multiplying each term by 5;

$5*\frac{3}{5}y+5*y=48*5\\3y+5y=240\\8y=240$

Dividing both sides by 8

$\frac{8y}{8}=\frac{240}{8}\\y=30$

Putting y=30 in Eqn 1

$x+30=48\\x=48-30\\x=18$

John caught 18 fishes and Peter caught 30 fishes.
