<em>Answer and Step-by-step explanation:</em>
<em>For this question the answer is : 375 g of that wonderful flour.</em>
<em>According to the question:</em>
<em>150 g flour is for 12 cakes
.</em>
<em>So, to find the missing value x g flour is for 30 cakes
</em>
<em>Now we form in the equation: </em>
<em>x = (150 x 30) : 12 = 375 g of flour
</em>
<em>
That's the final answer ! - 375g of four,</em>
<em></em>
<em>Here's another method:
</em>
<em>
according to the question:</em>
<em>150 flour is for 12 cakes
</em>
<em>So to find the missing value for 30 cakes
,</em>
<em>
</em>
<em>30 : 12 = 2.5
</em>
<em>150 x 2.5 = </em><em>375 g flour </em>
<em></em>
<em>and that's the final answer : 375g of the wonderful flour.</em>
