How do you do questions 3 and 4 and explain if you can.

Well for question 3 you could use algebra. if there are 4568 peaches and mangoes together and 1654 more peaches than mangoes. mangoes qill be our x and peaches will be x + 1654 because there are 1654 more peaches than mangoes. so since peaches + mangoes = 4568, x + 1654(peaches) + x(mangoes) = 4568, now we have to do the algebra. x + 1654 + x = 4568 , first collect like terms, x + x = 2x. 2x +1654 = 4568 now we subtract 1654 - 1654 and 4568 - 1654. 2x = 2914. now we do 2 divided by 2 and 2914 divided by 2. our answer is x = 1457, that's how many mangoes there are, now we do 1457 + 1654 to find out how many peaches there are, there are 3111 peaches. now let's check to see if we're right, 1457 + 3129 = 4568
