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

(a)

Add the ratio numbers to get $\var{numberone}+\var{numbertwo}+\var{numberthree}=\var{summ}$

Now divide the total length by this to work out the value of one part:

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

Now multiply this by each number in the ratio to give:

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

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

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

(b)

Use the same method as in part (i)

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

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

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

$\var{numberfour} \times \var{k}=\var{numberthree*k}$

(c)

$\var{ratioab[0]} + \var{ratioab[1]} + \var{ratioc}=\var{ratioab[0]+ratioab[1]+ratioc}$

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

$\var{money/(ratioab[0]+ratioab[1]+ratioc)} \times \var{ratioab[0]} = £\var{dpformat(ans31,2)}$

$\var{money/(ratioab[0]+ratioab[1]+ratioc)} \times \var{ratioab[1]} = £\var{dpformat(ans32,2)}$

$\var{money/(ratioab[0]+ratioab[1]+ratioc)} \times \var{ratioc} = £\var{dpformat(ans33,2)}$

Give a worked solution to the whole question.
