Question

Simplify 5 whole 7 upon 9 minus 1 whole 1 upon 3 minus 7 whole 11 upon 50

Answer 1

Answer:

-2\frac{349}{450}

Step-by-step explanation:

$5\frac{7}{9}-1\frac{1}{3}-7\frac{11}{50}=5\frac{350}{450}-1\frac{150}{450}-7\frac{99}{450}$

$9*50=450$

$3*150=450$

$50*9=450$

5\frac{7}{9}-1\frac{1}{3}-7\frac{11}{50}=5\frac{350}{450}-1\frac{150}{450}-7\frac{99}{450}

$5\frac{7}{9}-1\frac{1}{3}-7\frac{11}{50}=5\frac{350}{450}-1\frac{150}{450}-7\frac{99}{450}$

$4\frac{200}{450}-7\frac{99}{450}$

$-2\frac{349}{450}$
