1/2 the lengths of Sarah's string is equal to 2/5 of Daniel string Chris's string is 3 x Sarah's string. All together the strings are 6 feet long how long is Sarah's string
Let Daniels's string =S, then we have:
Sarah's string =1/2S*2/5=1/5 S
Chris's string =3*1/5 S =3/5 S
S + 1/5S + 3/5S =6, solve for S
S =10/3 =3 1/3 feet Daniel's string
1/2 * 10/3 =10/6 =1 2/3 feet-half of Daniel's string
2/5*10/6 =20/30 =2/3 feet Sarah's string
2/3 * 3 =2 feet Chris's string, so that:
3 1/3 + 2/3 + 2 =6 Feet.
