Gap-fill

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

A piece of $\var{material}$ $\var{lent}$ cm long is cut into three pieces in the ratio of $\var{numberone}$ to $\var{numbertwo}$ to $\var{numberthree}$ . Determine the lengths of the three pieces.

Gap 0.cm

Gap 1.cm

Gap 2.cm

Advice

Part 1:

Add the ratio numbers and then divide the length by the summed total

$\frac{\var{lent}}{\var{summ}}$

Then multiply each peice by the ratio length

$\var{numberone} \times \var{ratio}$

$\var{numbertwo} \times \var{ratio}$

$\var{numberthree} \times \var{ratio}$

Part 2:

Use the same method as in part 1

$\frac{\var{total}}{(\var{numberone1}+\var{numbertwo1}+\var{numberfour})}$

$\var{numberone} \times \var{k}$

$\var{numbertwo} \times \var{k}$

$\var{numberfour} \times \var{k}$

Part 4:

$(\frac{\var{money}}{(\var{ratioab[0]} + \var{ratioab[1]} + \var{ratioc})}) \times \var{ratioab[0]} = \var{ans31}$

$(\frac{\var{money}}{(\var{ratioab[0]} + \var{ratioab[1]} + \var{ratioc})}) \times \var{ratioab[1]} = \var{ans32}$

$(\frac{\var{money}}{(\var{ratioab[0]} + \var{ratioab[1]} + \var{ratioc})}) \times \var{ratioc} = \var{ans33}$
