Mazyrski [523]

Answer:

10\frac{29}{30}

Step-by-step explanation:

5\frac{1}{2} +3\frac{2}{3} +1\frac{4}{5}

Let us group the integers and the fractions.

5\frac{1}{2} +3\frac{2}{3} +1\frac{4}{5} = (5+3+1)+(\frac{1}{2} +\frac{2}{3}+\frac{4}{5}  )

= 9+\frac{15+20+24}{30}

= 9+\frac{59}{30}

=9+1\frac{29}{30}

=10\frac{29}{30}

Destiny designs necklaces.
Alex17521 [72]

Answer:

Step-by-step explanation:

Well, the ratio of yellow beads to blue beads is 4:5. The best way I think is to guess and check multiplying the ratio by integers. You need between 15 and 20.

4 : 5 ( = 9 too little )

8 : 10 ( = 18 just right)

12 : 15 ( = 27 too much)

So per necklace, 8 yellow beads and 10 blue beads would be needed. 

I hope this helps :-)
