We must use the mentioned proportions in Task 1, especially in a pie chart. Percentages: 10% increase, 25 per cent decrease, increased by 15%, dropped by 10 per cent, fall at 50%, reached to 75%, tripled, doubled, one-fourth, three-quarters, half, double fold, treble, 5 times higher, 3 timers lower, declined to about 49%, stood exactly at 43%. Fractions: 4% = A tiny fraction. 24% = Almost a quarter. 25% = Exactly a quarter. 26% = Roughly one quarter. 32% = Nearly one-third, nearly a third. 49% = Around a half, just under a half. 50% = Exactly a half. 51% = Just over a half. 73% = Nearly three quarters. 77% = Approximately three quarters, more than three-quarter. 79% = Well over three quarters. Proportions: 2% = A tiny portion, a very small proportion. 4% = An insignificant minority, an insignificant proportion. 16% = A small minority, a small portion. 70% = A large proportion. 72% = A significant majority, A significant proportion.89% = A very large proportion. 89% = A very la
