math @ home activity
find some prices of items around your home, in a store, or in an ad. have your child tell how many dimes it would take to make that amount. then have your child tell how many pennies it would take to make that amount.

Explanation:

Problem 3: \( 41.6 \div 0.1 \)

Step 1: Recall the rule of dividing by 0.1

Dividing a number by 0.1 is equivalent to multiplying the number by 10 (because \( \frac{1}{0.1} = 10 \)).
\( 41.6 \div 0.1 = 41.6 \times 10 \)

Step 2: Perform the multiplication

Multiplying 41.6 by 10 moves the decimal point one place to the right.
\( 41.6 \times 10 = 416 \)

Step 1: Recall the rule of dividing by 0.01

Dividing a number by 0.01 is equivalent to multiplying the number by 100 (because \( \frac{1}{0.01} = 100 \)).
\( 7.8 \div 0.01 = 7.8 \times 100 \)

Step 2: Perform the multiplication

Multiplying 7.8 by 100 moves the decimal point two places to the right.
\( 7.8 \times 100 = 780 \)

Step 1: Recall the rule of dividing by 10

Dividing a number by 10 moves the decimal point one place to the left.
\( 30.4 \div 10 \)

Step 2: Move the decimal point

Moving the decimal point in 30.4 one place to the left gives 3.04.
\( 30.4 \div 10 = 3.04 \)

Answer:

\( 416 \)

Problem 4: \( 7.8 \div 0.01 \)
