Activity 2

Note that $240 ~ mL \times 20 = 4800 ~ drops$ and $2 ~ hours \times 60 = 120 ~ mins$. Fill in missing values for each empty box.

Question 1

1. $120 ~ mL \times \fbox{?} ~ = \fbox{?} ~ drops$
2. $1 ~ hour \times \fbox{?} ~ = \fbox{?} ~ mins$

1. $120 ~ mL \times 20 = 2400 ~ drops$
2. $1 ~ hour \times 60 = 60 ~ mins$

Question 2

1. $240 ~ mL \over 2 ~ hours$ $\times$ $\fbox{?} ~ drops \over \fbox{?} ~ mins$ $=$ $4800 ~ drops \over 120 ~ mins$ = $\fbox{?} ~ drops/mins$

1. $240 ~ mL \over 2 ~ hours$ $\times$ $\fbox{20} ~ drops \over \fbox{60} ~ mins$ $=$ $4800 ~ drops \over 120 ~ mins$ = $\fbox{4} ~ drops/mins$
1. $120 ~ mL \over 1 ~ hour$ $\times$ $\fbox{?} ~ drops \over \fbox{?} ~ mins$ $=$ $\fbox{?} ~ drops \over 60 ~ mins$ $=$ $\fbox{?} ~ drops/mins$
1. $120 ~ mL \over 1 ~ hour$ $\times$ $\fbox{20} ~ drops \over \fbox{60} ~ mins$ $=$ $\fbox{2400} ~ drops \over 60 ~ mins$ $=$ $\fbox{4} ~ drops/mins$
