(i) \(\frac{2}{3}\) × 2 \(\frac{2}{3}\) = \(\frac{2}{3}\) × \(\frac{8}{3}\) = \(\frac{16}{9}\) = \(\frac{17}{9}\)
(ii) \(\frac{2}{7}\) × \(\frac{7}{9}\) = \(\frac{2}{9}\)
(iii) \(\frac{3}{8}\) × \(\frac{6}{4}\) = \(\frac{9}{16}\)
(iv) \(\frac{9}{5}\) × \(\frac{3}{5}\) = \(\frac{27}{5}\)= 1 \(\frac{2}{25}\)
(v) \(\frac{1}{3}\) × \(\frac{15}{8}\) = \(\frac{5}{8}\)
(vi) \(\frac{11}{2}\) × \(\frac{3}{10}\)= \(\frac{33}{20}\) = 1 \(\frac{13}{20}\)
(vii) \(\frac{4}{5}\)× \(\frac{12}{7}\) = \(\frac{48}{35}\) = 1 \(\frac{13}{35}\)
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
