Hi can you how can i solve these questions

49) 7/5 1+1/(2+1/2) 2/1+1/2=5/2 1/(5/2)= 2/5 1+(2/5)= 7/5 50)13/3 3+(1/2)+((1+(1/4))/(2-(1/4))) 1+(1/4)=5/4 2-(1/4)=3/2 (5/4)/(3/2)=5/6 3+(1/2)+(5/6)=13/3 51) 39/10 ((3/5)/5)+ (3/(4/5)) ((3/4)/(5/1))+((3/1)/(4/5)) (3/4)•(1/5)+(3/1)•(5/4) (3/20)+(15/4) (3/20)+(75/20) (78/20)=39/10 52)89/40g ((5/8)/(g))+((8/g)/(5)) (5/8)•(1/g)+(8/g)•(1/5) (5/8g)+(8/5g) (25/40g)+(64/40g)=89/40g

The answer is 270 cars.you can do this by making a proportional relationship. for instance, 200 is the whole we are using, so on a “number line” 200 would be over 100%. now, since he sells 35% more, add 35% to 100% to get 135% on the other side of the “number line” on the bottom half, leaving the top half empty.cross multiply 200 by 135 then divide by 100 to get your answer. i hope this , if it did, , if you don’t mind, giving me brainiest! 200/100% } 200 • 135 /100 ? /135%
