Gap-fill

Ask the student a question, and give any hints about how they should answer this part.

$\displaystyle \simplify[noc]{{d[0]}/{f[0]}}\;=$ Gap 0., $\;\;\displaystyle \simplify[noc]{{d[1]}/{f[1]}}\;=$ Gap 1., $\;\;\displaystyle \simplify[noc]{{d[2]}/{f[2]}}\;=$ Gap 2., $\;\;\displaystyle \simplify[noc]{{d[3]}/{f[3]}}\;=$ Gap 3.

Input as fractions and do not include brackets in your answer.

You can click on Show steps for help. You will not lose any marks if you do.

Advice

We have:

$\displaystyle \simplify[noc]{{d[0]}/{f[0]}}=\simplify[]{({a[0]}*{c[0]})/({b[0]}*{c[0]})}=\simplify[all]{{a[0]}/{b[0]}}$ . Common factor $\var{c[0]}$ .

$\displaystyle \simplify[noc]{{d[1]}/{f[1]}}=\simplify[]{({a[1]}*{c[1]})/({b[1]}*{c[1]})}=\simplify[all]{{a[1]}/{b[1]}}$ . Common factor $\var{c[1]}$ .

$\displaystyle \simplify[noc]{{d[2]}/{f[2]}}=\simplify[]{({a[2]}*{c[2]})/({b[2]}*{c[2]})}=\simplify[all]{{a[2]}/{b[2]}}$ . Common factor $\var{c[2]}$ .

$\displaystyle \simplify[noc]{{d[3]}/{f[3]}}=\simplify[]{({a[3]}*{c[3]})/({b[3]}*{c[3]})}=\simplify[all]{{a[3]}/{b[3]}}$ . Common factor $\var{c[3]}$ .
