Multiply the numerator and denominator by 7×2 = 14 to eliminate the denominators of those fractions:

$\dfrac{\dfrac37}{\dfrac{7\sqrt{10}}2}\times\dfrac{14}{14}=\dfrac{3\times2}{7\sqrt{10}\times7}=\dfrac6{49\sqrt{10}}$

Rationalize the denominator by multiplying both numerator and denominator by √10:

$\dfrac6{49\sqrt{10}}\times\dfrac{\sqrt{10}}{\sqrt{10}}=\dfrac{6\sqrt{10}}{49(\sqrt{10})^2}=\dfrac{6\sqrt{10}}{49\times10}=\dfrac{6\sqrt{10}}{490}$

Lastly, cancel the common factor of 2 in both the numerator and denominator (which comes from 6 = 2×3 and 490 = 2×245):

$\dfrac{6\sqrt{10}}{490}=\dfrac{3\sqrt{10}}{245}}$

Answer: Stacey now bakes 36 cinnamon bagels.

Step-by-step explanation:

Given: Each morning, Stacey makes 20 cinnamon bagels.

She has increased the number she bakes each morning by 80%.

Number of cinnamon bagels Stacey bake = 20+80% of 20

= 20+ (0.80)x 20 [To remove % , divide number by 100, So 80%=0.08]

= 20+16 [(0.80)x 20=16 ]

= 36

Hence, Stacey now bakes 36 cinnamon bagels.
