Answer:

Step-by-step explanation:

This problem is all about bases and exponents.  Because we have a quotient and the bases are both 5's, that means that we can use the rule of exponents for quotients to rewrite and simplify:

That's the simplification as long as you are "allowed" to leave the exponent as a negative number.

Tia cut 4 meter 8 centimeter wire into 10 equal pieces. Marta cut 540 centimeter wire into 9 equal pieces . How much longer is o
saveliy_v [14]

Answer:

19.2 centimeters

Step-by-step explanation:

Tia cut a 4 meter and 8 centimeter wire, converting this measure to centimeters

4m + 8 cm = 400cm + 8cm =408 cm

and she cut it into 10 equal pieces, thus each piece measures:

\frac{408cm}{10}=40.8cm.

Martha has a wire of 540 centimeter wich she cutted into 9 equal pieces, so each piece measures:

\frac{540cm}{9} =60cm

The difference between the two wires is:

60cm - 40.8cm=19.2cm
