Question

Josefina ate 3/8 of the pizza and Leando ate 4/16. How much did they eat between the two of them?​​

Answer 1

Addition of fractions:

To calculate how much they ate between the two of them, the amounts each ate must be added:

`\begin{gathered} \sf (3)/(8) + (4)/(16) = \\ \\ \sf(16 / 8 * 3 + 16 / 16 * 4)/(16) = \\ \\ \sf(6 + 4)/(16) = \\ \\ \sf (10)/(16) = \red {\boxed{ \sf ( \green5)/( \green8) }}\end{gathered}`

Therefore, between the two of them they ate five eighths of pizza.

To add heterogeneous fractions, fractions with different denominators, follow these steps:

• Find the common denominator, which is the least common multiple of the denominators.
• Divide the common denominator by the other denominator and multiply by the numerator.
• Write the results obtained above as numerators with the sign of the sum between them.
• Add the numerators.
• Simplify the result if possible.

Answer 2

To calculate how much they ate between the two of them, the amounts each ate must be added:

`\begin{gathered}\begin{gathered} \bold{ (3)/(8) + (4)/(16)} \\ \\ \bold{(16 / 8 * 3 + 16 / 16 * 4)/(16)} \\ \\ \bold{(6 + 4)/(16)} \\ \\ \bold{ (10)/(16) }= {\boxed{ \sf ( \bold5)/( \bold8) }}\end{gathered}\end{gathered}`

`\therefore` Between the two of them they ate five eighths of pizza.

To add heterogeneous fractions, fractions with different denominators, follow these steps:

Find the common denominator, which is the least common multiple of the denominators.

Divide the common denominator by the other denominator and multiply by the numerator.

Write the results obtained above as numerators with the Sign of the sum between them.
