Dana ordered 6 pizzas for her party and each pizza is sliced into quarters. She says in order to find out how many slices there are, she needs to calculate
6÷1/4. Which multiplication expression will also solve the problem of how many slices there are?
To solve the problem, Dana can either divide 6 by 1/4 or multiply 6 by the reciprocal of 1/4. This means, Dana can calculate it as follows:
6 ÷ 1/4 = 6 x 4/1 = 24
Therefore, Dana has 24 slices of pizza for her party. Alternatively, she can use the multiplication expression:
6 x 4 = 24
This will also give the same result, which is the total number of pizza slices.
To solve the problem of how many slices there are, Dana needs to calculate the division expression 6 ÷ 1/4. In order to find a multiplication expression that is equivalent to this division expression, we can use the concept of dividing by a fraction which is equivalent to multiplying by its reciprocal.
To calculate 6 ÷ 1/4, we need to invert the fraction 1/4 to obtain its reciprocal, which is 4/1.
So, 6 ÷ 1/4 is equivalent to 6 * 4/1, which can be simplified to 24/1 or simply 24.
Therefore, the multiplication expression that is also correct is 6 * 4.
