If 4 strings of length `(1)/(3)` metre were laid end to end, what would be the total length?

Explanation

3 strings of `(1)/(3)` metre make 1 metre, one.more string makes `1 (1)/(3)` metres Thus, 4 xx `(1)/(3)` metre is `1 (1)/(3)` metres Using only numbers, 4 xx `(1)/(3)` is `1 (1)/(3)` As multiplication, `4 xx (1)/(3)=1 (1)/(3)`
We can also think like this: 4 xx `(1)/(3)` métre means, 4 pieces of `(1)/(3)` mefres
`(1)/(3)+(1)/(3)+(1)/(3)+(1)/(3)=(t+1+1+1)/(3) mp (4)/(3)=1 (1)/(3)`
