a group of 80 ants went to collect some treacle. 10% lost their way 30% got eaten by a passing anteater how many ants came back

30% + 10% = 40%

40% = 0.40

0.40 * 80 ants = 32 ants

80 - 32 = 48

48 ants came back

Answer: 48

Step-by-step explanation:

you start off with 100% of ants

if 10% lose their way and 30% get eaten, the percent that comes back is

100 - 10 - 30 = 60%

so 60% of 80 is

(0.6 * 80) = 48 ants

so 48 ants come back
