1.How to find the total fraction of two books has keith read?
given that:
keith has to read 2 books for school. keith read 1/4 of the first book on monday and 3/5 if the second book on saturday.
Now, to find total fraction of these two books has keith read.
so, simply add the two fractions of these two books to obtain the total fraction.
Here keith read 1/4 of the first book
3/5 of the second book
[tex] \frac{1}{4} + \frac{3}{5} \\ \frac{5 + 12}{20} \\ \frac{17}{20} [/tex]
Hence the Total fraction of two books has keith read is 17/20
2. How to find the total number of students?
given that
One teacher has 5 slices of pizza. that means total slices of pizza is 5.
The teacher wants to give each student 5/8 of a slice of a pizza. that means a slice of pizza per each student is 5/8.
Now to find the total number of students by dividing total pizza by slice of pizza for each student.
[tex]no \: of \: students = \frac{total \: slices \: of\: pizza}{a \: slice \: of \: pizza \: for \: each \: students} [/tex]
[tex]no \: of \: students = \frac{5}{ \frac{5}{8} } \\ no \: of \: students = 5 \times \frac{8}{5} \\ no \: of \: students = 8[/tex]
Hence ,The total number of students are 8.
3. How to find the number of batches of tarts are made by joan?
given that
one batch of tarts needs 1/2 of a cup of flour.
joan has 8 cups of flour per batch of tarts.
[tex]8 \: cups \: of \: flour = \frac{16}{2} = 8[/tex]
then to find how many batches of tarts can joan make by 8 is divided by 1/2.
[tex] \frac{8}{ \frac{1}{2} } \\ \frac{8}{1} \times \frac{2}{1} \\ 16[/tex]
Hence 16 batches of tarts are made by joan.
