Answer: three- fourths = 21/28
Step-by-step explanation:
Hi, to answer this question we have to express the fractions in decimal form.
If both sides are equal the proportion is valid
• 3/4 = 21/28
0.75 = 0.75
• 5/6= 29/30
0.83333 ≠0.966666
• 4/7=16/49
0.57≠0.32
• 2/5=12/15
0.4 ≠0.8
So, the valid proportion is three- fourths = 21/28

The correct question is
The local currency it gives is a total of 275 Yuan. <span>If the yuan is worth 6.58 to a US$, what would the price to a US$ be if the yuan changed to 6.25
The </span><span>options are A)$2.21 B)$2.50 C)$13.31 D)$41.79 E)$44.00

</span><span>at the current exchange rate give (6.58)
</span>if 1 usd-----------------> 6.58 yuan
X usd------------------> 275 yuan
X=275/6.58------------> X=41.79 usd
at the current exchange rate give (6.25)
if 1 usd-----------------> 6.25 yuan
X usd------------------> 275 yuan
X=275/6.25------------> X=44 usd
so
the change in price in US$ would be [44-41.79]=US$2.21
the answer is the option
