to find out

How much flour did she use altogether

we know here flour use to make cake

so total flour is used = add both flour for vanilla and chocolate cake

total flour is used = $\frac{2}{5}$ + $\frac{3}{4}$

total flour is used = $\frac{23}{20}$

she use altogether flour is $1 \frac{3}{20}$ lb
