(a)
(i) As\(\frac{2}{3}\) × \(\frac{5}{10}\) = 10 / 30
Therefore, the number in the box, such that \(\frac{2}{3}\)× __ = \(\frac{10}{30}\) is \(\frac{5}{10}\)
(ii) The simplest form of \(\frac{5}{10}\) is \(\frac{1}{2}\).
(b)
(i) As \(\frac{3}{5}\) × \(\frac{8}{15}\) = \(\frac{24}{75}\).
Therefore, the number in the box, such that \(\frac{3}{5}\) × __= \(\frac{24}{75}\) is \(\frac{8}{15}\).
(ii) As \(\frac{8}{15}\) cannot be further simplified, therefore, its simplest form is \(\frac{8}{15}\).
Write equations for the following statements:
(i) The sum of numbers x and 4 is 9.
(ii) 2 subtracted from y is 8.
(iii) Ten times a is 70.
(iv) The number b divided by 5 gives 6.
(v) Three-fourth of t is 15.
(vi) Seven times m plus 7 gets you 77.
(vii) One-fourth of a number x minus 4 gives 4.
(viii) If you take away 6 from 6 times y, you get 60.
(ix) If you add 3 to one-third of z, you get 30
