how to convert 100 yards to meters? ( please show the process)
how many cm's in 1 inch?
2.54
site is a bit laggy...
\(\bf \left(\cfrac{1\cancel{ in }}{2.54\cancel{ cm }}\cdot \cfrac{100\cancel{ cm }}{1m}\cdot \cfrac{1yd}{36\cancel{ in }}\right)\cdot 100\\ \qquad \qquad \uparrow \\ \textit{how many yards in 1meter} \)
I dont get it
notice the measures equivalents 1in to 2.54cm 100cm in 1m 1yd to 36in then you cancell those units out.. and mulitply the fractions to get how many "yards in 1 meter" you got 100 yards.... thus multiply that much times 100
you'd usually put those equivalents in a fraction like above and simply put one above the other.... doesn't quite matter which goes above or below so you arrange them in a way that cancels out so in this case I wanted so cancel out say "cm" so in one of the fractions is below and in another fraction is above so it cancels out
the unit cancels out....but the value.... needs to be multiplied across, like in any fraction multiplication
so in the end the only units left, are "yards" and "meters"
now i think i get it thanks
\(\bf \left(\cfrac{1\cancel{ in }}{2.54\cancel{ cm }}\cdot \cfrac{100\cancel{ cm }}{1m}\cdot \cfrac{1yd}{36\cancel{ in }}\right)\cdot 100\\ \qquad \qquad \uparrow \\ \textit{how many yards in 1meter} \\ \quad \\ \implies \left(\cfrac{1}{2.54}\cdot \cfrac{100}{1}\cdot \cfrac{1}{36}\right)\cdot 100\implies \left(\cfrac{1\cdot 100\cdot 1}{2.54\cdot 1\cdot 36}\right)\cdot 100\)
