Please help with this question:


Jovi had 2 strings, string A and string B. Initially, string A was thrice the length of string B. Jovi then cut 9.1m from string A and 140cm from string B. The length of string B became 1.5 times of string A. What was the length of string A at first?

Thanks!

Need help for the following questions:


1. String A was 12m shorter than String B. 4/9 of String A and 1/6 of String B were cut off. The remaining length of String B was twice the remaining length of String A. How long was String B at first?


2. At a seminar, 20 of the participants are females. Halfway through 3/4 of the males left the seminar. If 1/6 of the original number of participants are now males, find the number of people at the seminar at first.

Thanks,
wkong

HI,

3 mangoes cost $5
so 1 mango cost $(5/3)

Number of mangoes = p / (5/3)
= p x (3/5)
= 3p/5 mangoes

Hi

Need your help to solve the following Math P6 question?

Four boys A,B,C & D bought a present for their mum and they shared the total cost of the present.
A paid 2/5 of the total amount paid by the other 3 boys.
B paid 1/2 of the total amount paid by the other 3 boys.
C paid 1/3 of the total amount paid by the other 3 boys.
If D paid $30 less than C, what was the cost of the present?

Thanks.
