1.a: In total, there are 380 people in the group, and 200 of them are men. The rest are women. We can set up the subtraction problem 380-200 and get 180 as a result. This means that THERE ARE 180 WOMEN.
We can check our work by adding 180 women and 200 men, and we get 380 as a result.
1.b: In total, there are 380 people. Since 130 of them voted for party b, we can set up the equation 380-130, and find out that there were 250 people who voted for party a. Since 120 of the people voting for party a are men, if we set up the equation 250-120, we can subtract the 120 men and find out only how many women voted for party a. THERE ARE 130 WOMEN VOTING FOR PARTY A, because 250-120=130.
2.a: There are 48 adults in total, and based on the pie chart showing adult’s favorite subjects, half of them chose English. We can find half of 48 by dividing it by 2. Since 48 divided by 2 is 24, 24 ADULTS CHOSE ENGLISH.
2.b: REESHMA IS WRONG. While one quarter of adults and one quarter of children chose maths, there were 48 adults were surveyed and only 32 children surveyed. One quarter of 48 is 12, but one quarter of 32 is only 8.
