Answer:
5[tex]\frac{1}{3}[/tex]
Step-by-step explanation:
Glass: [tex]\frac{2}{3}[/tex] × 10
Hours: 1[tex]\frac{1}{4}[/tex]
1) Find the real value. He drinks [tex]\frac{20}{3}[/tex] glasses of water in 1[tex]\frac{1}{4}[/tex] hours. 1[tex]\frac{1}{4}[/tex] × [tex]60[/tex] gives us the minutes because 1 hour is 60 minutes.
Glass : Minutes:
[tex]\frac{20}{3}[/tex] : [tex]75[/tex]
2) Use ratio to find the value of one. 60 ÷ 75 gives us 0.8. Multiply [tex]\frac{20}{3}[/tex] by 0.8 or [tex]\frac{8}{10}[/tex].
Glass : Minutes
[tex]\frac{16}{3}[/tex] : 60
3) Convert [tex]\frac{16}{3}[/tex] into a mixed number.
= 5[tex]\frac{1}{3}[/tex]
