jok3333 [9.3K]

For 5 taccos 2 cups cheese is needed.

So 10 taccos is 2*(5 taccos)=2*2 cups cheese =4cups

\begin{gathered} As\text{ 5 taccos=2cup cheese} \\ 1\text{ tacco=}\frac{2}{5}\text{cup cheese} \\ As\text{5 taccos=2cup cheese} \\ 1\text{ cup cheese=}\frac{5}{2}\text{taccos} \\ So\text{ 10 tacco=10}\ast\frac{2}{5}\text{cup cheese=2}\cdot2=4\text{cups} \\ 10\text{ cup cheese =10}\ast\frac{5}{2}\text{tacco}=5\ast5=25tac\cos  \end{gathered}35\text{ taccos}=35\ast\frac{2}{5}=7\cdot2=14\text{ cup cheese}24\text{ cup cheese=}24\ast\frac{5}{2}=12\ast5=60tac\cos

So to convert taccos to cups of cheese multiply by 2/5 and from cups of cheese to taccos multiply by 5/2.

Weird question but, whenever you divide by 1/4 or multiply by 4/1, will you always get the same answer.
professor190 [17]

Answer:

yep

Step-by-step explanation:

when you divide a fraction u can use the KCF method which is basically:

(keep) the first fraction the same

(change) the division sign in the middle to a multiplication sign

(flip) the second fraction

basically because you have to flip the 1/4 when you divide it, it'll be the same as a 4/1 anyways

A lake has an area of 63800000000 square meters.
Leno4ka [110]

Answer:

64,000 (2 s.f)

Step-by-step explanation:

1 km is 1000 metres

so, 1 km² = 1000 x 1000 m²

i.e. 1 km² = 1,000,000 m²

=> 63,800,000,000/1,000,000 = 63,800

The second significant figure is 3 --> 3000

so, to the nearest 1000 we have 64,000 (2 s.f)

Hope it help and if it is correct please give brainliest

Thank You
